本文研究了Cu、Zn、Co,Mn、Fe离子在D—751大孔氨羧螯合树脂中的吸着行为、pH影响、定量吸着条件,并用火焰原子吸收法测定海水中痕量Cu,Zn、Mn、Fe、Co离子,还测试了D—751树脂对Cu、Zn、Mn、Fe离子的交换容量分别为2.50、1.96、1.89,2.11mmol/g,平衡速率分别为15.30、10.25分钟以及Cu、Mn离子交换曲线.
In this paper, the adsorption behavior of Cu, Zn, Co, Mn, Fe ions in D-751 macroporous carboxylated chelating resin was investigated. The influence of pH and the conditions of adsorption were studied. The trace amounts of Cu and Zn in seawater were determined by flame atomic absorption spectrometry Mn, Fe and Co ions. The exchange capacities of Cu, Zn, Mn and Fe ions for D-751 resin were also tested. The exchange capacities of Cu, Zn, Mn and Fe ions were 2.50, 1.96, 1.89 and 2.11 mmol / g, respectively. The equilibrium rates were 15.30 and 10.25 minutes, Mn ion exchange curve.
