摘要: 关于控制水体中重金属含量的因素,六十年代以来文献陆续有所报导.在海水体系中粘土矿物对重金属的固定作用的研究,较早期的有Chester(1965)的伊利石吸附海水中钴和锌的研究.近五年来又见有Rermers[1]、Murray[2]、Meyers[3]、O'conner[4]、Weijden[5]以及Robin[6]等进一步分别探讨了粘土矿物对重金属吸附作用的影响因素、吸附能力及吸附动力学等问题,其中有的还提出了吸附作用的模式.Abstract: The water of the Changjiang River contains a large quantity of suspended solid matters,among which illitic,Montmorillonitic and kaolinitic clays are predominant.These colloidal clays consist of two parts:one is coated with inorganic or organic matters,and another is not.Both have the funceion of fixing heavy metals on their surface in various degrees.This paper reports the simulation experiments of the adsorptions of Cr,Cu and Hg (from semi-saline water)on montmorillonite,illite,etc.
