摘要
利用香蕉皮制成吸附剂,对含有Pb2+ 的模拟废水进行吸附。分别对吸附剂粒径、pH值、废水中Pb2+ 初始浓度、吸附时间及吸附剂投加量条件对吸附程度进行考察。实验结果表明,香蕉皮吸附的最佳条件为:香蕉皮粒径为100目,pH=5,废水中Pb2+ 浓度50mg/L,吸附时间为90min,香蕉皮投加量为0.5g,最高吸附量为9.16 mg/g,在此条件下,100mL水样,30℃条件下,香蕉皮对Pb2+ 吸附率在90%以上。

Abstract:
Banana peel was made from adsorbent for adsorption of Pb2+ from simulated wastewater.The adsorption efficicncy of adsorbent grain size,pH,initial Pb2+ concentration,adsorption time and banana peel dosage was investigated. The experiment results showed that the optimum operating conditions were banana peel grain size of 100 meshes, pH of 5.0,Pb2+ concentration of 50 mg/L , adsorption time of 90 min and banana peel dosage of 0.5g, the adsorption capacity of banana peel reached to 9.16 mg/L, Under these conditions, more than 90%of Pb2+ was removed from 100 mL of simulated wastewater at 30℃.
