将锌试剂用简单搅拌的方法负载在D-290型大孔阴离子交换树脂上制成锌试剂负载树脂.考察了该树脂在酸碱溶液中的稳定性,吸附金属离子的选择性,对Cu~(2+)的吸附速率和吸附容量等特性;试验了柱上定量吸附和洗脱Cu~(2+)的实验条件;建立了用该负载树脂经柱法分离富集后原子吸收测定自来水中及ZuSO_4、CdCl_2等盐类中微量铜的分析方法.
The zinc reagent was loaded on the D-290 macroporous anion exchange resin by simple stirring process to make the zinc reagent loaded resin.The stability of the resin in acid-base solution, the selectivity of adsorbed metal ions, (2 +) adsorption rate and adsorption capacity. The experimental conditions for the quantitative adsorption and elution of Cu 2+ were studied. A method was developed for the determination of copper ion And ZuSO_4, CdCl_2 and other salts trace copper analysis method.
