摘要

采用氟离子选择电极，利用Matlab或Excel进行多元回归分析，测定了25℃、0.01 mol L−1 (NH4)2SO4离子强度条件下，Th（IV）和Al（III）氟化物的稳定性常数。结果表明，氟化氢配合物的总稳定常数为β1 = 621.45, β2 = 6.34 × 103。对于氟化钍配合物，β1 = 3.59 × 105, β2 = 1.89 × 1010, β3 = 6.58 × 1014, β4 = 1.42 × 1019。对氟化铝复合物,β1 = 3.27×105,β2 = 6.53×1010,β= 5.16×1014,β4 = 5.00×1017,分别和β5 = 2.18×1019。

Determination of stability constants of fluoride complexes of Th(IV) and Al(III) by potentiometry with ion selective electrode

Using a fluoride ion selective electrode and multivariate regression analysis conducted with Matlab or Excel, the stability constants of Th(IV) and Al(III) fluorides were determined at 25 °C and 0.01 mol L⁻¹ (NH₄)₂SO₄ ionic strength. The results indicate that the overall stability constants for hydrogen fluoride complexes were β₁ = 621.45 and β₂ = 6.34 × 10³. For thorium fluoride complexes, they were β₁ = 3.59 × 10⁵, β₂ = 1.89 × 10¹⁰, β₃ = 6.58 × 10¹⁴, and β₄ = 1.42 × 10¹⁹, respectively. For aluminum fluoride complexes, they were β₁ = 3.27 × 10⁵, β₂ = 6.53 × 10¹⁰, β₃ = 5.16 × 10¹⁴, β₄ = 5.00 × 10¹⁷, and β₅ = 2.18 × 10¹⁹, respectively.
