Abstract Biochar is a promising candidate for the sustainable remediation of soils, especially those contaminated with cationic heavy metals, because its liming effect and tunable surface functionality. Despite potential, prior studies have highlighted biochar's limitations in immobilizing soil oxyanions, such as arsenic (As) antimony (Sb), particularly short term. This shotcoming primarily attributed to an increase pH following biochar amendment, factors like competition phosphate. In this study, amendments were applied three soils varying levels oxyanions including As Sb, cations cadmium (Cd) lead (Pb). These treatments generally resulted short‐term failure oxyanion immobilization. However, noteworthy phenomenon unfolded over 2‐year period, where biochars gradually transitioned from initial mobilization or poor immobilization eventual successful (up 87.0% 100% Sb). Temporal changes Cd Pb differed exhibiting no improvement rates time. Potential mechanisms driving process investigated, suggesting decline pH, progressive oxidation carbon fractions, direct adsorption effects contributing factors. study sheds light on temporal shift performance, highlighting gradual efficacy The findings offer valuable insights into dynamic nature capabilities.
