【 摘 要 】

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 ºC, with removal of more than 80% of phenol.
