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。
Zirconium nitrate complex was studied by cation exchange method. When [H ~ +] = 3 mol / l and ionic strength (μ = 3) were constant, the distribution ratio of zirconium in solution to resin phase at different [NO_3 ~ -] was determined and the Franzus method was used to calculate the zirconium level The stability constant of nitrate complex is β_1 = 0.76. In this case, zirconium is mainly present in the solution in the form of Zr 4+ and Zr 3+.
