摘要：

The isolation of porphyrins for geochemical research requires multistage concentrations from ≤0.1% to >95% purity. In meaningful studies of porphyrin concentration the criteria of enrichment, recovery, purity, and time, need to be considered. The present study was therefore undertaken with the aim of optimizing these parameters, in the systematic concentration of 31 ppm of mixed vanadyl porphyrins (VOP) from 2 kg of powdered New Albany shale. The following preparative scale operations were carried out: extraction, deasphaltation, medium-performance liquid chromatography (MPLC), precipitation, and solid phase bonded sulfonic acid (RSO3H) extraction, which are frequently used to precede high-pressure liquid chromatography (HPLC). The overall scheme gave a 9000-fold enrichment, 60% overall recovery, 23% pure VOP, and required approximately 80 h (2 weeks) of time. © 1990, American Chemical Society. All rights reserved.
