Preparação e caracterização de argilas organofílicas à base de um polímero biodegradável e sua aplicação no tratamento de Águas residuais

Abstract

Growing industrialization has contributed negatively to the maintenance of natural water resources through the disposal of wastewater into the environment without adequate treatment. Faced with this problem, water reuse appears to be a promising solution for reducing water source pressure. However, to reuse this precious resource it is necessary to go through a treatment process to remove contaminants. Among the various treatment methods, the adsorption-filtration method using organophilic clays stands out. However, conventional organophilic clays pose a problem related to public health and the environment when they are poorly handled and discarded. In the present study, the use of organophilic clays based on a biodegradable polymer as an adsorbent material was explored. Namaacha's bentonite is calcium by nature and to make it sodium it was activated with 2% Na 2 CO 3 . The surface modification was carried out with polymeric activation using polymer (fatty acid polyamide), followed by the characterization of the material using analytical techniques and finally kinetic studies were carried out. The research results show that the use of these clays can be a viable and efficient alternative to conventional organophilic clays
