Abstract
In the current investigation, a new insight into the adsorptive interaction of iron–silicon mixed oxide with arsenate was proposed through comparative studying the behavior of arsenate on the mixed oxide and on the parent oxides, i.e., iron hydroxide and silica. All the oxides were characterized by using different physiochemical methods. The arsenate concentration, pH, temperature, co-ion effect, and calcination of adsorbents were the key parameters of this investigation. The Langmuir model was used for the interpretation of the adsorption data. The thermodynamic parameters and spectroscopic evidences of the samples before and after arsenate adsorption confirmed that the mechanisms of arsenate adsorption by Fe(OH)3 and mixed oxide showed close similarity.
