Protecting ecosystems and human health from potentially toxic elements (PTEs) like Cd(II) and As is critical. The results showed that SnZVI particles were uniformly dispersed in biocarbon matrix. The pseudosecond- order kinetics and Langmuir model can better match the adsorption process of Cd(II) and As(III) by SFC., with the maximum removal capacity of 405 mg·g−1 and 349 mg·g−1, respectively. Biochar enhances electron transport and prevents S-nZVI agglomeration. The removal mechanisms of SFC, including chemical precipitation, ion exchange and oxidation, shows great potential for remediation of PTEs pollution in irrigation water.
