在1mol/L NaClO_4+HClO_3(pH1.5)介质中,25±0.5℃下,用固态膜硫氰酸根离子选择电极研究了UO_2~(2+)-SCN~-络合平衡体系,求得络合物的稳定常数logβ_1=0.70,logβ_2=2.38。与文献结果基本一致。
The equilibrium membrane system of UO_2 ~ (2 +) - SCN ~ - was studied by solid state membrane thiocyanate ion selective electrode in 1mol / L NaClO_4 + HClO_3 (pH1.5) medium at 25 ± 0.5 ℃. The stability constants of compounds logβ_1 = 0.70, logβ_2 = 2.38. The results are basically the same as the literature.
