摘要
目的 建立刺梨对重金属砷的吸附模型,探讨其吸附机理.方法 通过检测与刺梨粉达吸附平衡的溶液中砷含量来绘制吸附等温线.结果 吸附量随浓度增加而线性上升,以后逐渐变慢,最后趋于稳定.结论 本模型与实验结果相吻合,初步确定刺梨的解毒机制是以物理吸附为主.
aim setting up an absorption model of rose roxburghii tratt to heavy metal arsenic, and discussing the absorption mechanism; Method rendering absorption isotherm by measuring the content of arsenic in the mixture in which the rose roxburghii tratt powder can reach the absorption balance; Result the absorption raise linearally by the increasing consistence of arsenic firstly, then decrease gradually and tend to stability at last： Conclusion this model tallies with the experiment result, and we can conclude that physical absorption is a dominant force in rose roxburghii tratt＇s detoxification mechanism.
