本文制定了利用N,N′-乙撑双(乙酰丙酮亚胺)为螯合剂,反相色谱分离测定镍和铜的方法。研究了螯合物形成和分离的最佳条件及其它离子的干扰,用于废水测定取得了满意结果。
In this paper, a method for the determination of nickel and copper by reverse phase chromatography using N, N’-ethylenebis (acetylacetonimine) as chelating agent has been developed. The optimum conditions for the formation and separation of chelates and the interference of other ions were studied, and the satisfactory results were obtained for the determination of wastewater.
