Abstract

The presence, in water, of organic compounds that present health risks, such as herbicides, has caused great interest in the technique of adsorption by activated charcoal. The activated charcoal (AC) is a microporous adsorbent which can be obtained from a variety of carbonaceous materials, its adsorbent power comes from its large surface area and from the presence of a variety of functional groups at its surface with, for example, internal surface area and high porosity capable of adsorbing various types of compounds, among them, the herbicides. This study aims to obtain activated charcoals from agricultural residues, sugarcane bagasse and Moringa oleifera peel, so they can be used efficiently and competitively in the elimination of the herbicides atrazine, and hexazinoa and tebuthiurom in the water through the adsorption process.
