Abstract

Abstract

This study systematically investigates the influence mechanisms of impurity ions such as Fe³⁺, Si⁴⁺ and Al³⁺ on interfacial emulsification in the solvent extraction of gallium. Through factorial experiments combined with characterization techniques such as FT-IR and SEM-EDS, it was found that Fe³⁺ induces phase separation due to co-extraction into the organic phase, while Si⁴⁺ hydrolysis products, specifically SiO₂, form a stable three-dimensional network structure at the interface, which is identified as a key factor for emulsification. Based on Pickering emulsion theory, calculations reveal that SiO₂ particles exhibit the highest adhesion energy at the oil-water interface, demonstrating the strongest interfacial stabilization capability. This research provides theoretical insights and technical support for preventing and controlling emulsification during gallium extraction.
