摘要
选择了6种常用的变色酸双偶氮类试剂作为稀土树脂相显色剂,初步探讨了影响树脂吸附率的因素。实验表明,在硝酸介质中,在大量NO_3^-存在下,三氯偶氮胂和三溴偶氮胂可应用于稀土树脂相分光光度法。
Six common diazoderivatives of chromotropic acid as coloring reagents on resin phase were selected for determination of rare earth. The factors of affecting resin adsorption ratio arc preliminarily discussed. The experimental results showed that in the medium of nitric acid, trichloroarsenazo and trioromoarsenazo may be used to resin phase spectrophotometry of rare earth, when a large number of nitrate exist.
