【摘要】 用Fe3+对活性炭进行修饰,用于吸附水中的砷。结果表明,活性炭改性的最佳条件为:活性炭与12 000 mg/L的Fe3+溶液,在1∶100(g/mL)的情况下,振荡3 h,Fe3+吸附率近40%。活性炭对砷的吸附属于物理吸附,全过程无其他离子引入水中,不会对水体造成二次污染。获得了一种新的从饮用水中去除砷的方法。更多还原

【Abstract】 Activated carbon with a modified Fe3+for the adsorption of arsenic.The result indicated that the optimum condition of activated charcoal modified were as follows: the concentration of Fe3+solution was 12 000 mg / L,solid-to-liquid ratio is 1 ∶ 100(g / mL),and oscillation for 3 h,the adsorption rate near 40%.Additionally,the adsorption of As(V) by the modification of activated charcoal belongs to physical adsorption,therefore,this method do not bring other ions into the water.A new remarkable method of remove the nocuous residual chlorine from the drinking water was got.更多还原
