Separation Behaviors of Aluminum(III) and Indium(III) Complexes with 1-Phenyl-3-methyl-4-benzoyl-5-pyrazolone in High-performance Liquid Chromatography

Aluminum- and indium-PMBP chelates were prepared and separated by liquid chromatography on an ODS column using acetonitrile as a mobile phase. The retention time of indium chelate varied significantly with a mobile phase of acetonitrile containing sodium chloride.
