Metal Speciation in Natural Waters and Metal Complexing with Humic Matter

摘要

The stability constants of metal and humic matter complexes extracted from different soils were calculated. Speciation of metals in natural waters was determined taking into account their chemical composition and content and properties of organic matter. We established metal speciation in water objects with account for competitive reactions resulting in formation of hydroxide, hydrocarbonate, sulfate, and chloride metal complexes and obtained a competitive series of metal activity in natural waters of the zones considered.
