Abstract
The production of active metal complexes as a source of micronutrients is still highly desirable. In this study, metalloporphyrin compounds (i.e., iron, magnesium, and zinc) were obtained by modifying sodium-copper chlorophyllin. Metalloporphyrins were prepared by a multi-step process involving protonation of sodium-copper chlorophyllin, followed by complexation of porphyrin with selected metal salts in a DMSO solution. The selected metalloporphyrins were analysed in terms of stability, metal content, and process yield using UV-Vis, FT-IR, and ASA methods. Analysis of the influence of the pH of the complexing system and the molar ratio of chlorophyllin and metals showed that it is possible to obtain metalloporphyrins of Mg, Zn, and Fe with metal bonding efficiencies of 20, 40, and 90%, respectively. The type of acid, its concentration, and the type of salt used in the processes were also critical factors in the protonation of porphyrin as well as the efficiency of metal-porphyrin bonding.
