Arsenate [As (V)] removal kinetics in aqueous solutions using modified nanosized zerovalent iron (Fe0) particles such as NiFe and PdFe was studied. The objective was to examine the efficiency of these modified particles in arsenate removal under varying conditions. These particles were synthesized through the borohydride reduction of nickel and palladium salts on Fe0 particles. Employing pseudo-first-order rate equations, it was found that arsenate removal kinetics were satisfactorily described, with the removal rates indicating that NiFe particles achieved up to 2.5 times higher kinetics compared to zerovalent iron. In contrast, PdFe particles demonstrated a lower removal rate. Further experiments evaluated the effects of initial arsenate concentration, temperature, and competing inorganic anions on the removal process. Results reveal that increasing temperatures significantly enhanced arsenate removal, while the presence of competing anions like phosphate and sulfate inhibited the efficiency of arsenate removal. These findings highlight the potential of modified zerovalent iron particles in environmental remediation applications, specifically in arsenate contamination scenarios.
