竹炭对水中重金属离子的吸附

简述了竹炭的结构及其性质,归纳了竹炭的改性特点及改性方法,其主要改性方法有化学浸渍法、高温热处理法、载物法及复合法;总结了几种竹炭对水中重金属离子的吸附效果及再生效果,分析了p H值、重金属离子初始浓度、吸附时间、反应温度及竹炭本身性质等因素对竹炭吸附重金属能力的影响,探讨了吸附机理,并展望了改性竹炭的应用前景。

Bamboo Charcoal Adsorbent Heavy Metal Ions from Aqueous Solutions

This paper introduce the structure a nd quality of bamboo charcoal, and conclude the character and ways of modification, such as chemical resistance, high temperature heat treatment, loading method and composite algorithm. This paper talk about the adsorption mechanisms and the influences, such as pH, initial heavy metal ions concentrations, ad-sorbent dosage, reaction temperature and itself feature. What is more, applying prospect of modified-bamboo charcoal in wastewater treatment is also presented.
