Adsorption Characteristics of Directly Modified Bentonite

Abstract:

Directly modified bentonite was obtained by directly adding modifier cetyl trimethyl ammonium bromide (CTMAB) to sodium bentonite.The modified bentonites adsorption performance to methyl orange and methylene blue was studied, and it was compared with modified bentonite prepared by classical method. The results show that directly modified bentonite has a greater and faster absorption for both methyl orange and methylene blue; the relationship between adsorption quantity and equilibrium concentration conforms to the Langmuir isotherm equation; absorption kinetics is in accordance with the secondary dynamics equation.
