Feasibility of a Chemical Washing Method for Treating Soil Enriched with Fluorine Derived from Mica

High levels of fluorine in soil may pose health risks and require remediation. In this study, the feasibility using a practical chemical washing method for removal from an enriched was evaluated. The procedures were optimized through experimental analyses various solutions conditions (i.e., solution concentration, solid–liquid ratio, agitation speed, reaction time). Additionally, effects techniques improving efficiency, such as ultrasonic washing, aeration, multi-stage Herein, among all applied methodologies, maximum efficiency achieved total present only 6.2%, which indicated that inefficient remediating particular soil. Further sequential extraction analysis showed chemically stable form (residual fraction), possibly because presence mica minerals. It demonstrated not be effective soils containing forms fluorine. these cases, other physical-based remediation technologies or risk management approaches more suitable.
