摘　　要：研究了竹炭的粒径与用量、吸附时间、温度以及磷(Ⅴ)离子初始浓度等因素对磷(Ⅴ)离子去除率的影响.研究结果表明:竹炭对磷(Ⅴ)离子吸附去除率随其粒径的减小而增大,而随其用量的增加而增大;磷(Ⅴ)离子初始浓度增大,竹炭吸附率减小;竹炭对磷(Ⅴ)离子的吸附可在180min达到平衡,最佳吸附温度为30℃.竹炭是较为理想的吸附磷(Ⅴ)离子的材料.The effects of such factors as the particle size and the dosage of the bamboo charcoal, the absorbing time, the temperature as well as the initial concentration of Phosphorus（Ⅴ）ions on the removing of Phosphorus（Ⅴ）ions are investigated. The results show that the adsorbing rate increases with the decrease of the particle size of bamboo charcoal. And with the increase of the dosage of bamboo charcoal, the adsorbing rate increases. While the initial concentration of Phosphorus（Ⅴ）ions increases, the adsorbing rate decreases. The adsorption can reach equilibrium in 180min. and 30℃ is the best absorbing temperature. Bamboo charcoal is an ideal absorptive material for the removing of Phosphorus（Ⅴ）ions.
