本文研究了用铜离子选择性电极测定微量锆的方法,提出在0.2M醋酸-0.4M醋酸钠-0.1M磺基水杨酸的介质中,有一定量的Cu~(2+)-EDTA存在下,可定量测定锆,分析范围为3×10~(-6)～1×10~(-4) M,标准锆(5.0×10~(-6)M)的测定精密度为4%。大量的U(Ⅵ),Al~(3+)和微量的Ca~(2+),Cr~(3+),Mg~(2+),Mn~(2+),Mo(Ⅵ),Ti~(4+),W(Ⅵ),Cl~-,SO_4请下载后查看，本文暂不支持在线获取查看简介。(2-)等不干扰测定。方法较为简便。
In this paper, the method of determination of trace zirconium with copper ion selective electrode was studied. It was proposed that in the presence of Cu ~ (2 +) - EDTA in 0.2M acetic acid-0.4M sodium acetate-0.1M sulfosalicylic acid , The zirconium can be quantitatively determined, the analytical range is from 3 × 10 -6 to 1 × 10 -4 M, and the determination precision of standard zirconium 5.0 × 10 -6 M is 4%. A lot of U (Ⅵ), Al 3+ and trace amounts of Ca 2+, Cr 3+, Mg 2+, Mn 2+, Mo (Ⅵ), Ti ~ (4 +), W (Ⅵ), Cl ~ -, SO_4 Please download to view, this article does not support online access View profile. (2-) do not interfere with the determination. The method is simple.
