| Abstract: | The adsorption characteristics of alder sawdust on As3＋ in water was investigated.The effects of pH,temperature and Hg2＋ on the adsorption rate of As3＋ in water were studied.The best conditions of alder sawdust adsorbed As3＋ in wastewater were as follows：the optimal pH was controlled at around 4.0—6.0 and the adsorption temperature was 20℃.When Hg2＋ and As3＋ were concurrence,increase of Hg2＋ concentration made for adsorption of As3＋,and the adsorption of alder sawdust on As3＋ fit pseudo-second-order dynamic equation.The results showed alder sawdust has good application foreground in preparation of adsorption material for As3＋. |
