抄録

The adduct formation and the masking effect due to the addition of neutral ligands to mobile phase were applied to improve the mutual separation of some metal chelates of 3-mercapt-1,5-diphenylformazane (dithizone) in reversed-phase high-performance liquid chromatography. The addition of trioctylphosphine oxide and triethanolamine (TEA) was effective for controlling the retention time of some metal dithizonates. The addition of TEA made it possible to separate the overlapped peaks of nickel(II) and zinc(II) dithizonates from each other. On the other hand, 1,10-phenanthroline (phen) masks Ni^II and Zn^II selectively depending upon stabilities of their charged phen complexes. The degree of the masking effect of phen was predictable to some extent from the stability constants of the metal dithizonates and the metal–phen complexes.
