阳离子交换法研究锆-硝酸根络合物

STUDY OF ZIRCONIUM NITRATE COMPLEX BY CATION EXCHANGE

摘要: 应用阳离子交换法研究了锆-硝酸根络合物。当H~+=3 mol/l,离子强度(μ=3)不变时,测定不同NO_3~-下锆在溶液与树脂相间的分配比,并引用Franaeus方法计算锆的一级硝酸根络合物的稳定常数β_1=0.76。这时锆主要以Zr~(4+)和Zr(NO~3)~(3+)形式存在于溶液中。

Abstract: Zirconuim nitrate complex is investigated by cation exchange. With H~+=3mol/l, μ=3 and varied NO_3~-, the distribution ratios of Zr in solution to Zr inresin. phase are determined, and the stabality constant of primary nitrate complexof zirconium is calculated by Fronaus' method, β_1=0.76. The zirconium existsmainly in the form of Zr~(4+) and Zr (NO_3)~(3+) in the solution.
