摘要
利用一步凝胶法合成了钙型腐植酸树脂，用自制树脂装柱，控制柱平衡液的ｐＨ为５～６并以０．０１ｍｏｌ／ＬＨＣｌ为洗脱液，使Ｃａ２＋、Ｍｇ２＋离子与其它１２种离子定量分离。可应用于铝合金中常量及微量镁的测定，回收率可达９８．６％～１０４％。该法分离效率高。
Calcium humic acid resin is synthesized by one step gel method. With the column filled with the resin made,the column poiser kept at pH 5～6, and with 0.01 mol/L HCl as an eluent, Ca 2+ , Mg 2+ can be separated quantitatively. This method could be applied to the determination of macro magnesium and micro magnesium in duraluminum. The percent recovery is 98.4%～104%. The advantages of the method are high separation efficiency and good selectivity.
