用吸光光度法研究了Nd~(3+),Ho~(3+),Er~(3+)离子与1-苯基-3-甲基-4-二氟乙酰基吡唑酮-5(PMDCP)和喹啉(Quin)三元体系的超灵敏跃迁现象,测定三元配合物的组成比为Ln~(3+):PMDCP:Quin=1:4:1:试验了该体系在光吸收最大时遵守比耳定律的浓度间隔;同时对某些干扰离子进行了试验以及对混合试样的测定。
The effects of Nd ~ (3 +), Ho ~ (3 +), Er ~ (3+) ions and 1-phenyl-3-methyl-4-difluoroacetylpyrazolone-5 (3): PMDCP: Quin = 1: 4: 1: The system was tested for its optical absorption At maximum, the Beer’s Law concentration intervals are followed; some interfering ions are tested and the mixed samples are determined.
