研究了铜、铅、镉离子在巯基纸上的吸附性能与pH值的关系.结果表明：金属离子吸附于巯基纸上的稳定性随酸度降低而增大,铜、铅离子在pH=1时仍然能被吸附于巯基纸上,并不随溶剂的展开而移动,镉离子则需在pH=3及更高时才能稳定吸附于巯基纸上.在1mol/L的HCl条件下,铜、镉混合液在层析纸上能够有效地分离.控制不同的条件（例如,pH值）,可以容易地分离水溶液中的多种重金属离子.

the relationship of adsorption behavior of copper ion, lead ion and cadmium ion on the sulfhydryl paper with pH of the solution was studied. The result showed： the stability of metal ions adsorption on sulfhydryl paper decreased with solution acidity increase. Copper ion and lead ion was still adsorbed on the paper even pH-- 1 of solution, stopped the origin not moving with spread solvent on the paper. Cadmium ion was adsorbed on the paper stably only pHi3. Copper ion was separated from cadmium ion on the sulfhydryl paper in 1 mol/L of HCI solution. Multiple heavy metal ions in solution could be separated each other by sulfhydryl paper by control different conditions as pH value.
