摘    要:本文研究了Mg^2+、Ca^2+、Sr^2+在活性炭上吸附作用以及环境条件对这种吸附作用的影响。实验表明,它们在活性上的吸附强度顺序为Mg^2+〈Ca^2+〈Sr^2+,吸附作用符合表面络合吸附模式,以简化络合反应模式计算出的表面络合形成条件稳定常数大小顺序与试验结果一致。

关 键 词:吸附 活性炭 碱土金属

Abstract:In this paper, the absorption of Mg2 , Ca2 and Sr2 on acti-vated carbon panicles was studied as a function of pH,concentrations of absorption was strongly pH - dependent and all the ab-sorption isotherms were in agreement with Freundlich Equation. All tested ions were absorbed mainly in the form of ion and the strength of absorption was increased from Mg2 to Sr2 .Theabsorption could be explained by the surface complexation mod-el. Conditional absorption constants of surface complexes of Mg2 Ca2 and Sr2 with activated carbon particles were calculated by a simplified surface complex model.
Keywords:Adsorption Activated carbon Alkaline earth metal ions
