摘　　要：以柚子皮粉末为生物吸附剂,考察其对Fe^(3+)的吸附性能。重点通过静态吸附实验考察了吸附剂用量、溶液pH值、Fe^(3+)初始浓度、吸附时间以及吸附温度等对吸附效果的影响。在pH值为2.5和25℃下,设计正交试验确定了最佳吸附条件,即柚子皮的用量为2.0 g,Fe^(3+)的初始浓度为0.27 mmol·L^(-1),吸附时间为3 h。在实验所确定的最优条件下,柚子皮粉末对Fe^(3+)的吸附率可达到54%,且重现性和精密度良好,可用于吸附废水中的Fe^(3+)。The adsorption properties of pomelo peels powder for Fe^(3+)were investigated.The effects,such as the amount of adsorbent,pH value of solution,the initial concentration of Fe^(3+),adsorption time and temperature,were investigated by static adsorption experiments.Under the conditions of pH value of 2.5 and 25℃,the optimum adsorption conditions were determined by orthogonal experiment.The initial concentration of Fe^(3+)was 0.27 mmol·L^(-1),the amount of adsorbent was 2.0 g,and the adsorption time was 3 h.The adsorption rate of pomelo peels powder for Fe^(3+)can reach 54%on the optimal conditions.And the reproducibility and precision were good,which could be used to adsorb Fe^(3+)in wastewater.
