Hexavalent chromium [Cr(VI)] presents substantial environmental and health hazards due to its pronounced toxicity and mobility in soils. Traditional chemical reduction methods for Cr(VI) are often inadequate for treating chromium-contaminated soils, as they may fail to fully reduce Cr(VI), leading to incomplete remediation. Consequently, there is a critical need to develop more efficient and environmentally sustainable methods for the treatment of hexavalent chromium. This study explores an innovative approach using microwave-enhanced reduction of soil iron minerals facilitated by tea polyphenols to achieve transformational fixation of Cr(VI). The microwave-assisted treatment (0.5 wt% TP combined with MW at 700 W for 10 min) significantly reduced Cr(VI) concentrations in iron-rich soil from 363.4 mg kg
