| Abstract: | The paper Presents the studies of hypersensitive transition of the ternary system of Nd~(3 ), Ho~(3 ), Er~(3 ) ions with 1-phenyl-3-methyl-4-dichloroacetylpyrazolone-5(PMDCP) and diphenylguanidine(DPG) and the determination of the component ratio of ternary coordination compound in solution(Nd~(3 ):PMDCP: DPG=1:4:1) by spectrophotometry. The concentration range of this system obeying Beer's law at the maximum of absoption of light has been tested. The test of some interference ions have been performed. |
