摘　　要：以人居生活废弃物生物质炭为材料,探讨生物质炭对重金属镉离子吸附去除的影响因素。结果表明,生物质炭对Cd2+吸附量随其粒径减小而增大。pH对Cd2+吸附量的影响不显著,但生物质炭加入后提高了溶液pH,特别对初始pH低的溶液提高幅度更显著。研究显示,可通过调控生物黑炭的粒径及控制pH优化人居生活废弃物生物质炭来去除污染水体中的Cd2+。The influencing factors of biomass carbon adsorption of cadmium ions were explored u-sing living waste biomass charcoal.The results showed that the capability for biochar to adsorb Cd2＋ decreases with increasing particle size.Meanwhile,the effect of pH on Cd2＋ adsorption was not significant,but the carbon biomass increased the pH during the adsorption,and the greatest effect was expected for the lower initial pH of the solution.This study shows that that the re-moval for Cd2＋ with living life biochar can be controlled by regulating the biological waste bio-mass black carbon particle size and controlling the pH.
