用高效液相色谱仪研究了铯在石英上的吸附行为。Cs在石英表面的分配系数（Ka）是在pH值为6 ~ 11、离子强度为10 - 3 M ~ 10 - 1 M的溶液中测定的。的Ka值被认为是随着pH值的增加和离子强度的降低而增加。用双电层模型对所得数据进行了分析，得到了双电层静电和吸附反应的最佳参数值。在此基础上，对吸附机理进行了探讨。
The adsorption behavior of Cs onto quartz was investigated with the use of a high performance liquid chromatograph. The surface-based distribution coefficient (Ka) of Cs onto quartz was determined in the solution of which pH ranged from 6 to 11 and ionic strength from 10−3 M to 10−1 M. The Ka values were found to increase with increasing pH and with decreasing ionic strength. The obtained data were successfully analyzed by an electrical double layer model and the optimum parameter values of the double layer electrostatics and adsorption reactions were obtained. The adsorption mechanisms of alkali metal ions was discussed on the basis of the present analysis.
