摘要

研究了纤维素材料(石竹花)和角质材料(羊蹄)对pb2 +和mn2 +离子的吸附性能。在30℃条件下采用间歇法进行了实验,考察了初始金属离子浓度和接触时间对实验结果的影响。对于纤维素和角质材料,pb2 +和mn2 +离子分别在60和120分钟内达到等量浓度。平衡数据符合Freundlich吸附等温线。本研究表明,野果花和羊蹄可以作为吸附水中pb2 +和mn2 +离子的替代吸附剂。

Comparism of Adsorption Behaviour of Caryota Rumphia na Flower and Goat Hooves to Lead and Manganese Ions in Aqueous Solution
The adsorption of Pb 2+ and Mn 2+ ions by cellulosic (Caryota rumphiana flower) and keratinous (Goat hooves) materials was investigated in order to compare their adsorptive capability. The experiments were carried out by batch method at 30℃ and the effect o f initial metal ion concentrations and contact time were evaluated. Pb 2+ and Mn 2+ ions attained equi- lib riu m within 60 and 120 minutes respectively for both cellulosic and keratinous material. The equilib riu m data fitted the Freundlich adsorption isotherm. This study demonstrated that Caryota rumphiana flower and Goat hooves could be used as an alternative adsorbent to remove Pb 2+ and Mn 2+ ions fro m aqueous solution.
