Aproveitamento da glicerina proveniente da produção de biodiesel na obtenção de híbrido de caulinita para adsorção de Cr 3+

Abstract

The aim of this work was to contribute to the creation of new ways of treating wastewater contaminated with Cr3 +, based on solid-liquid adsorption. An adsorbent material was prepared by functionalization of kaolinite with glycerin biodiesel by-product. This material was tested for adsorption performed using a batch method, and results showed that inclusion of glycerin in the structure of kaolinite led to a significant increase in the capacity of Cr3 + adsorption. This contributes to the allocation of by-product of biodiesel and to the treatment of effluents from tanneries.
