摘要:
对海水中Zn（Ⅱ）,Ca（Ⅱ）,Cd（Ⅱ）与高岭石、伊利石和蒙脱石等粘土矿物;无定形水合氧化铁、α-FeOOH等铁的水合氧化物; δ-MaO2, γ-MnOOH,水锰矿等锰的水合氧化物等30个左右实验体系的液-固界面台阶型动力学曲线进行了系统的实验测定和全面的条件研究。在实验测定上提出两种方法、互为校核。对动力学曲线之台阶的消长和变化规律作了系统研究,确定主要影响因素是:金属离子初始浓度、固体交换剂量、体系的pH值和温度,以及搅拌速度等。

Abstract:
This article made an experimental determination systemalically and comprehensive condition studies of the plateau type kinetic curve of liquid-solid interface for the thirty systems Zn (II), Cu(II), Cd(II) with clay minerals (kaolinite, illite and montmorillonite), hydrous ferrec oxide (amorphous ferric oxide, geothite and hematite) and hydrous manganese oxide (-MnOOH, Manganite and -MnO2) etc. in seawater. The four main factors that decide the growth, decline and change of “plateau type” kinetic curves are: (1) initial concentration of metal ion, (2) quantity of solid exchanger (or solid-liquid ratio), (3) pH values of the system, (4) experimental temperature of the system.
Key words:  Liquid-solid Interface, Plateau type kinetic curve
