Estudia el proceso de oxidación avanzada utilizando sulfato de cerio como fotocatalizador en la degradación del colorante reactivo Azul 19 (C22H16 Na2ClN2O11 S3) en aguas residuales textiles. La Industria Textil es la segunda en el mundo después de la Industria de petróleo en generar más efluentes contaminados con colorantes azoicos que son tóxicos, cancerígenos y mutagénicos. La creciente contaminación ambiental nos obliga a estudiar un nuevo método de descontaminación eficiente, versátil y económico. El trabajo de degradación del colorante reactivo Azul 19 usado en procesos textiles cuyas aguas residuales son tratadas con peróxido de hidrógeno, radiación ultravioleta y catalizador sulfato de cerio, se basan en la capacidad de generación de radicales OH°, especie con un elevado potencial de oxidación mediante la combinación de un agente oxidante (H2O2) y radiación ...

The current research aims to reassess no traditional meats that in sausage shape get to entry in the local market, according to their nutritional qualities, such as low cholesterol and high protein, which shows the alpaca meat against pork, and also revalue mutton. The presence of Gigartina chamissoi (seaweed) in the formulation is important as a source of iodine, complex polysaccharides (fiber) and natural gelling agents which increase its biological value. Gigartina chamissoi besides raise its nutritional value, constitutes a prebiotic product for counter propensities against cancer cells in tissues such as mucous (esophagus, stomach), glandular (breast) and glandularvessels (prostate). To this effect has been developed an experimental design allowing manufacture sausages in more optimal hygienic conditions. The proximal chemical analysis of the finished product (Table 9) showed that F...

Zeolites have a negative charge on their surface; preferentially attract cations and scarcely anions such as and PO which are components of fertilizers. To modify the surface characteristics of the natural clinoptilolite type zeolite, sieved on 14 mesh, it was washed several times with distilled water, dried and placed in colloidal suspension of ferric hydroxide Fe(OH)3 for 24h. The zeolite was washed with distilled water and then it dried at 60°C for 2h. To evaluate the adsorption capacity of natural and modified zeolite, the adsorption isotherm was determined at different phosphate concentrations.The evaluation of the phosphate concentration before and after the adsorption process was determined by spectrophotometry, a method that is based on the formation of the blue ammonium phosphomolybdate complex (λmax=650nm), by reaction of a reducing solution of ammonium molybdate and ascorbic...
