含有隣-胂酸基-隣-羟基偶氮官能团的有机试剂,系由庫兹湼佐夫提出,并在分析中得到了越来越广泛地应用。例如:钍试剂用于测定钍、鋯、四价铀,四价钚、铍、鲤;偶氮胂用于测定六价铀、希土元素、锆、铝及其他元素。鉴于此,研究这些试剂及其合成的化合物、测定的pH影响和反应机理,具有极大意义。近来,开始了钍试剂、偶氮胂及其化合物的研究工作。其中,某些工作的缺点是对介质pH影响的研究范围较窄,结果使得对实验数据的解
Organic reagents containing o-arsonyl-o-hydroxyazo functionalities were proposed by Kuznetsov and have been used more and more widely in the analysis. For example: thorium reagents for the determination of thorium, zirconium, tetravalent uranium, tetravalent plutonium, beryllium, carp; arsenazo for the determination of hexavalent uranium, rare earth elements, zirconium, aluminum and other elements. In view of this, it is of great significance to study these reagents and their synthesized compounds, determine the pH effect and the reaction mechanism. Recently, the research work on thorium reagents, arsenazo and its compounds began. Among them, the disadvantage of some of the work is the narrow scope of the study on the effect of media pH, the result of the solution to the experimental data
