説明

Studies on liquid chromatography (LC) of metal complexes by our group are critically reviewed. In the third chapter is described gel permeation chromatography (GPC) of metal complexes of, β-diketones. The distribution coefficient, Kav, for every metal complex depended much on the solvent used. Practical GPC was regarded as one based on a combined function of size exclusion effect and partition effect. Introducing the concept of a regular solution to a phase system of GPC, the contribution of the partition effect could be estimated from the solubility parameters of solute, solvent and gel, the degree of gel swelling, and molar volume of the solute. Solubility parameter was the most useful guide for choice of the solvent to be used. In the fourth chapter, the HPTLC or HPLC behavior of porphyrin metal complexes is described. The effects of stationary phase material and mobile phase solvent on the retention of various porphyrins and porphyrin metal complexes were investigated. The effects of the ligated metal ion of complex and the chemical structure of ligating porphyrin were also studied. Reversed phase HPLC and HPTLC were successfully used for separation of several porphyrin metal complexes. In the fifth chapter was introduced the application of LC to analysis of petroleum samples, especially with respect to the vanadium- or nickel-containing species in the samples. By use of both GPC and HPLC equipped with rapid-scanning UV-visible spectrophotometric detector and AAS, several vanadium species as porphyrin complexes were separated and detected.
