利用改性花生壳吸附废水中Pb^(2+)的应用研究

Applying Modified Peanut Shell to Adsorption Pb^(2+) in Waste Water

对花生壳进行化学改性,引入对金属离子作用更强的活性基团,改善其吸附能力。研究了不同改性条件下,改性后花生壳对Pb2+吸附能力的影响,通过正交试验,确定最佳的吸附条件及其对吸附效果的影响。模拟废水试验,对Pb2+的吸附效率达64.32%。

This project through chemical modification to introduce a more active group to improve its aclsorptlon capacity, liae enects of modified conditions, effect of modified peanut shell adsorption capacity of Pbz＋ after through the orthogonal experiment to determine the best conditions of adsorption and the size of influence to the adsorption effect. Finally, doing competitive adsorption experiment , and at the same time doing simulated wastewater adsorption experiment, studying that the adsorption efficiency of the simulated wastewater is 64.32%.
