Abstract

The adsorption capabilities of active blue by sodium base and modified bentonite was studied in this paper.The influence of the dosage of bentonite,the initial pH,temperature,adsorption time and initial concentration of active blue on the adsorption effects were investigated.The composite bentonite was characterized by CEC,SEM and IR.Testing results showed that the modified bentonite have strong adsorbing capacities to active blue,the maximum adsorbtion capacities to the active blue is 1020.4 mg/g for the modified bentonite respectively which had been improved 23 times than the sodium base bentonite.
