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℃.

Key words: banana peel Pb²⁺ adsorptive property
