Abstract To explore the effects of iron-based silicon on the bioavailability and transformation of cadmium (Cd) and arsenic (As) in soil, laboratory long-term flooding cultivation culture adsorption experiment were carried out with Cd/As mild co-contaminated soil. Different proportions of Fe-Si materials and various iron-silicon salt (FS) components in combination with humic acid (FSC) and metal oxide (FSCa) were studied in the Cd-As soil. The morphological changes of Cd and As in the soil treated with the above complex agents were evaluated. The results showed that the ratio of iron to silicon was increased by 10%, the soil pH value was decreased by 0.35. Under F₂-S₈ treatment, ionized Cd in the soil was decreased by 71%. F₁₀-S₀ treatment reduced As ion state by 59.9%, and the content of ionized Cd and As were inversely proportional to the application ratios of iron salts and silicates. The intersection of Cd and As passivation rates between F₄-S₆ and F₆-S₄ was found to be between 25%~30%. Soluble Cd was the main compound of total Cd in soil, representing approximately 58%; As was mainly present in Fe-Al oxidation state and Ca binding state, accounting for 40% and 23% of total As, respectively. The ratios of iron to silicon from about 5.0:5.0 or 5.5:4.5 could effectively convert Al-bound As and Fe-Al oxide-bound As to Ca-bound As and residue state As. Meanwhile, soluble Cd can be converted into carbonate state Cd and Fe-Mn oxides state Cd. In conclusion, the bioavailability of Cd and As in soil can be simultaneously reduced by iron-based silicon compounds.
