Abstract: The absorbing performance for sulfide in wastewater was investigated under different conditions by using microwave and hydrochloric acid modified bentonite.The results showed that modified bentonite could enhance evidently absorption capability of sulfide.Some factors affecting absorption include absorption time,temperature,pH and bentonite consumption.According to the absorption isotherm curves of sulfide on modified bentonite,the regularity of absorption was fit to freundlich isothermal absorption model.B...
