摘　　要：以原子吸收分光光度计为分析手段,研究了CaSO4晶须对镉、镍、铅离子吸附性能。研究表明:铅离子在pH值为3～13范围内均可被CaSO4晶须定量吸附,尤其在pH值为8、振荡时间为2h时,吸附率高达77.89%;而对镉和镍两种金属离子几乎没有吸附作用。By means of atomic absorption spectrophotometer ,the absorption behaviors of calcium sulfate whisker to Cd （Ⅱ）,Pb （Ⅱ） and Ni （Ⅱ） ions were studied. The results showed that ： a quantitative ion absorption was found in the pH range of 3 - 13 for Pb, especially at pH 8 ,t=0.5h ,the absorption rate was up to 77.89%： However, absorption is hardly obtained for Cd and Ni ions .The research is useful for treating wastewater containing lead or analysis and separating trace lead.
