花生壳生物质炭对铅离子去除效果的研究

Study on Adsorption of Lead Ions by Biomass Charcoal from Peanut Shell

以花生壳为前驱体制备生物质炭,然后用高锰酸钾对生物质炭进行改性,通过比较改性前后两种生物质炭对溶液中铅离子的吸附性能,结果表明改性后的花生壳生物质炭的吸附性能明显优于改性前,饱和吸附量达到130.6 mg/g,是一种高效吸附剂。

Precursors to peanut shells system for biomass carbon and then modified by potassium permanganate biomass carbon,by comparing before and after the modification of two kinds of biomass charcoal adsorption performance of lead ion in the solution,the results showed that modified peanut shell biomass charcoal adsorption performance is better than before modification,saturated adsorption amount is 130.6 mg/g,it is a kind of efficient adsorbent.
