摘　　要：通过浊度滴定、浮选剂基团电负性计算和X射线光电子能谱测试等方法,研究了CF药剂与金属离子(Zn2+、Pb2+、Fe3+)的螯合能力以及与矿物表面的作用机理。结果表明,Zn2+、Pb2+和Fe3+与CF药剂反应生成难溶于水的螯合物;CF药剂通过其中的O、O与矿物表面上的金属离子螯合而形成O·O型五元环表面配合物。In this paper,the chelating ability,the interaction mechanism between CF collector and the metal ions(Zn^(2+),Pb^(2+) and Fe^(3+)) on mineral surfaces have been examined by means of nephelometric titration,XPS tests and the calculation of the group electronegativity of the flotation reagent.The results show that water insoluble chelating products are formed in the reaction between the metal ions and the O-,O() possessed by CF (collector) by the formation of O·O type five-ring surface chelates on mineral surfaces.
