Research on adsorption properties of basic brilliant green dye wastewater by bentonite and zeolite

In this paper, the sorbent bentonite and zeolite was used to treat the wastewater including basic brilliant green dye were investigated respectively. During this experiment, the quantity of sorbent, the surge time, the concentration of basic brilliant green dye and the pH of the solution, which make different effect on the rate of absorption, have been researched. And the remarkable adsorption conditions of the two sorbents were made certain. The conclusions indicated that when the quantity of bentonite was 25 mg and the surge time was 30 minutes, the absorption rate was over 94%, and when the quantity of zeolite was 180 mg and the surge time was 30 minutes, the absorption rate reached over 92%. So it shows that the adsorption effect of the bentonite is superior to the zeolite, and all they have wide application market.
