EFFECT OF MINERAL SYSTEMS ON COPPER AND ZINC REMOVAL FROM AQUEOUS SOLUTION PART I | Journal of ....

The role of mineral systems in copper and zinc elimination was examined in this study. The interactions of kaolinite, montmorillonite, goethite, and their mixes with copper and zinc ions were studied in batch mode at room temperature. This research looked at the reactivity and removal kinetics of mineral-metal interactions in water bodies that have been contaminated with copper and zinc ions. Copper and zinc removal was found to be dependent on particle size (15-60 m for kaolinite and montmorillonite, and 25-100 m for goethite, according to the data supported by an empirical model). In addition, the sorption process included intra-particle diffusion. Inner sphere complexation and outer sphere complexation were used to remove copper and zinc. Mineral mixing slowed the mass transfer rate of copper. In both the slow and quick response phases, this was in relation to single mineral systems. Different reactive sites were implicated at the start of adsorption.
