Nuestro equipo investigador, en colaboración con la empresa Grupo Interlab, S.A. (Madrid), lleva varios años involucrado en un ambicioso proyecto que ha llevado al mercado un instrumento optoelectrónico para análisis y control medioambiental e industrial. El sistema multicanal utiliza sensores y biosensores sobre fibra óptica basados en indicadores específicos resultantes de la ingeniería molecular y fotoquímica de complejos luminiscentes de Ru(II). De esta forma, se ha conseguido un novedoso dispositivo capaz de monitorizar simultáneamente por vía óptica, in situ y en continuo, diversos parámetros esenciales en calidad de aguas y procesos industriales (oxígeno, temperatura, pH, amonio, DBO, hidrocarburos, detergentes y pesticidas de tipo carbonato) mediante el simple cambio de terminal sensible situado en el extremo de la fibra óptica, ya que todos los indicadores preparad...

In the present work the revision, deduction and application of mathematical models in the quantification of the reaction kinetics of leaching processes of national sulphided minerals in chemical systems is made. The interaction between the mineral particles and the leaching solution is controlled by three possible mechanisms: by chemical reaction, by diffusion through the porous bed and by mass transfer; Each mechanism has its own mathematical modeling and parametric conditions. Experimental runs of leaching of gold and copper minerals are presented, in which their kinetic control equations of the most relevant variables are shown. Other empirical models are also shown that are used to elucidate the phenomenology of the leaching of mineral species, call chalcopyrite, sphalerite and galena.

Our research team, in collaboration with the company Grupo Interlab, S.A. (Madrid), has been involved in an ambitious project for several years that has brought to the market an optoelectronic instrument for environmental and industrial analysis and control. The multichannel system uses optical fiber sensors and biosensors based on specific indicators resulting from molecular and photochemical engineering of luminescent Ru(II) complexes. In this way, a novel device has been achieved capable of simultaneously monitoring optically, in situ and continuously, various essential parameters in water quality and industrial processes (oxygen, temperature, pH, ammonium, BOD, hydrocarbons, detergents and pesticides). carbamate type) by simply changing the sensitive terminal located at the end of the optical fiber, since all the custom-made indicators are excited by the same light and emit luminesce...

The chemical composition and apparent digestibility of nutrients of the solid-state fermentation (SSF) of waste taro tubers (Colocasia esculenta (L) Schott) inoculated with natural yogurt fed to growing pigs was determined. Dry matter (DM), organic matter (OM), crude protein (CP), crude fibre (CF), ash, ether extract (EE), nitrogen-free extracts (NFE) and gross energy (GE) were determined. For the study of apparent digestibility of the MS, MO, CP, CF, NFE and GE, 12 castrated Landrace x Duroc x Pietrain male pigs of 25 ± 2 kg were used, distributed in three groups with four animals each and fed with diets containing 0, 10, and 20% of SSF (T0, T10 and T20, respectively). The SSF presented high content of DM (83.33%), OM (93.77%), CP (13.95%), NFE (72.78%) and GE (4162.13 kcal kg MS-1) and low levels of EE (1.50%), CF (5.54%) and ashes (6.23%).

The chemical industry has showed steady growth in recent years and, as a result, the rate of intoxication has increased from the use of dangerous substances by employees of manufacturing companies. Therefore, small & medium enterprises (SMEs) in this industry must be committed to ensuring and guaranteeing safe and ergonomic workstations for employees that are mostly exposed to these risks to prevent incidents and reduce rates to a minimum when handling chemicals to produce paints and varnishes, and, at the same time, improve employee motivation and productivity. For this reason, this paper proposes the implementation of a safety management model based on process standardization and 5S for the purpose of promoting best practices in occupational safety and health, thereby reducing the number of intoxications within company grounds through employee collaboration in the improvement and optim...

Traditional methods of leather production in Peru consume on average between 60 to 80% of chromium for tanning process , generating wastewater with high concentrations of total chromium that must be treated in order to meet the Maximum Allowable Values ( VMA ) established by the DS 029-2009 - Vivienda. The use of complexing agents in the chrome tanning process reduces the supply of chromium to increase skin absorption. The main objective of this study was to evaluate the treatability by chemical precipitation of wastewater from traditional and alternative tanning process. It was determined that the optimal pH for the precipitation was between 7.36 and 9.99, the doses used besides sodium hydroxide were between 0.5 and 5.5 g / L, is the traditional process that requires higher dose . It was determined that the cost of the inputs used in the production of wet blue leather is more than the c...

The response surface methodology was applied to evaluate the optimal experimental conditions to remove persistent organic compounds from a synthetic textile wastewater using a batch photochemical reactor on a laboratory scale. Four factors at three levels were studied: Fenton H2O2/Fe2+ reagent ratio (11,25, 18,75, 26,25 mg/L/mg/L), UV lamp power (4, 11, 18 W), pH (2, 3, 4) and treatment time (60, 120, 180 min). The optimum levels found for the four factors were: ratio of Fenton H2O2/Fe2+ reagents equal to 17 mg/L/mg/L, UV lamp power equal to 4 W, pH equal to 3 and treatment time of 180 min. It was found that the photo- Fenton process is very effective in treating synthetic textile wastewater, with a removal of 86 %, with respect to COD.

The fatty acids trans form during the partial hydrogenation of oils, and is the present process that the national industrialist for the elaboration of the fat uses, for the elaboration of margarine. Studies have indicated problems in the health by the oil consumption with fatty acids trans, reason why it is required to have other alternatives of process that does not generate fatty acids trans, in the present investigation has considered as objective to obtain a greasy base for margarine without fatty acids trans, using the reaction of chemical interesterification for a mixture of oil of soya and palm, which was catalyzed with metóxido of sodium. The conditions of reaction were for the mixture of triglycerides a proportion in weight of 1:3 of oil of soya and palm, 1% in weight of catalyst and one temperature of 140ºC, that were optimal after the variance analysis, corresponded to the f...

The search for new protein sources for food formulation is increasing. Black soldier fly (Hermetia illucens) larvae have high levels of protein, good fat content and are rich in essential amino acids, making them an alternative source of dietary protein. In this work, the nutritional properties and metabolomic characterization of black soldier fly larvae meal native to the Peruvian Amazon reared on three organic waste substrates were carried out. The three meals had a high protein content (38.90-44.68%), lipids (26.96-31.01%), as well as a high potassium, calcium and low sodium content. The larvae meal fed with orange bagasse presented the best content of iron and manganese. The fatty acid profile showed a high content of palmitic, oleic and linoleic acids for the three flours. The most abundant essential amino acids in the three meals were leucine, lysine and valine. A total of 48 compo...

El objetivo de la investigación fue determinar el efecto de la recuperación de agua clarificada sobre el consumo de insumos químicos en el tratamiento de efluentes de la empresa Austral Group S.A.A. (2023). Se aplicó un enfoque cuantitativo de tipo preexperimental, con diseño longitudinal retrospectivo, utilizando la observación directa como técnica y fichas de registro como instrumento para caracterizar el sistema y cuantificar el consumo de reactivos. Los resultados mostraron que el sistema presentó un tiempo de retención hidráulica promedio de 2,49 horas y operó entre 138 y 154 días por año, recuperando un efluente con bajo contenido de sólidos y grasas. Tras la implementación, se registraron ratios promedio de consumo de 0,184 kg/m³ para sulfato férrico, 0,065 kg/m³ para Polychem 8420 y 0,058 kg/m³ para Polychem 8750, evidenciando reducciones cuantificables respect...
