The Oryza sativahusk is usually discarded and incinerated without control, which is why in the present investigation it was given an alternative use by means of its transformation into different adsorbent materials coded as HRKOH, ACARROZ and ACFeO. (CAC for commercial activated carbon), the activation of the husk was carried out in a chemical way using Caustic Potassium at 40% this to lyse lignocellulosic structures; subsequently, a metal oxide was added chemically. The process was optimized through a multilevel factorial design, the maximum yield was recorded by the HRKOH material and was 94.45%, however, due to its low porosity and consequently low retention of pollutants, it was not considered a competent material., the field tests regarding the adsorption of hydrogen sulfide showed similar behaviors between ACarroz, ACFeO and CAC, so it was decided to contrast the material ACARROZ v...
