近年来关于稀土分析的专著和综述相继发表。但讨论离子选择电极分析稀土的报道甚少。一般认为离子选择电极虽然是简易有用的工具,用於稀土分析尚存在困难。我们经过数年的探索研究,认为离子选择电极在稀土分析中,还是有一定的应用价值。本文拟就国内外这方面的进展和研究趋势分电极制备,稀土化合物中稀土与非稀土的分析、非水溶剂中稀土的电位滴定以及稀土配合物稳定常数的测定四方面进行讨论。 (一)稀土离子选择电极的制备 In recent years, monographs and reviews on rare earth analysis have been published. However, there are few reports about ion-selective electrode analysis of rare earths. Although generally considered ion selective electrode is a simple and useful tool for rare earth analysis is still difficult. After several years of exploration and research, we believe that the ion-selective electrode in the rare earth analysis, or have some value. This article intends to discuss the progress and research trends both at home and abroad in the preparation of electrode, analysis of rare earth and non-rare earth in rare earth compounds, potentiometric titration of rare earth in nonaqueous solvents and determination of the stability constants of rare earth complexes.
