生物质炭对溶液中镉的吸附研究

Study on adsorption of cadmium on biomass charcoal in aqueous solution

为探究废弃生物质材料利用的新途径,本文选择由水稻秸秆、玉米秸秆和稻壳经350~500℃热裂解制成的生物质炭作为吸附剂,研究了其对溶液中Cd^(2+)的吸附特性,考察了pH值、时间、溶液初始浓度及生物质炭投加量对吸附效果的影响。

In order to open up a new way of utilizing waste biomass materials,this paper selects biomass charcoal made from rice straw,corn straw,and rice husk by pyrolysis at 350~500℃as the adsorbent and studies its adsorption characteristics for Cd^(2+)in aqueous solutions.The effects of pH,time,initial concentration of the solution,and the amount of biomass charcoal added on the adsorption efficiency were investigated.
