Preparação e utilização de uma argila esmectítica organofílica como absorvente de fenol

Abstract

The main goal of this research, was the preparation and use of a organophilic smectitic clay able to promoting the adsorption of phenol. In this work was used a natural, clay called Chocolate, from Campina Grande - PB (Brazil). The natural clay was treated with a solution of sodium, carbonate. After this the sodium clay was treated with quaternary ammonium salt. The adsorptive study was conducted by different values of pH and. temperature. The results showed a better performance in adsorptive at pH 7 and temperature 30 °C, with removal of more than 80% of phenol.
