摘　　要：探究废纸脱墨污泥基活性炭在Fe(Ⅲ)去除方面的应用可行性。研究结果表明:废纸脱墨污泥基活性炭在活性炭含量为7.5g/l和Fe(Ⅲ)溶液浓度100mg/l,将水溶液pH调到2的条件下吸附3h,对Fe(Ⅲ)的吸附最优。动力学实验结果表明:废纸脱墨污泥活性炭对Fe(Ⅲ)的理论饱和吸附量为40.87mg/g,吸附能力常数为0.029L/g。The application feasibility of Fe(Ⅲ)absorption by deinked sludge-based activated carbon was discussed in this paper.The results showed that when the activated carbon content is 7.5 g/L,the concentration of Fe(Ⅲ)solution is 100 mg/L and adjusting the p H of the aqueous solution to 2 for 3 hours,the removal efficiency of Fe(Ⅲ)can be the best.The results of kinetic experiments showed that the theoretical saturated adsorption capacity of Fe(Ⅲ)for deinked sludge activated carbon is 40.87 mg/g,and the adsorption capacity constant is 0.029 L/g.
