ABSTRACT
The adsorptive removal of a pollutant from water is significantly affected by the presence of coexisting ions with various concentrations. Here, we have studied adsorption of arsenate [As(V)] by calcined Mg-Fe-(CO3)-LDH in the presence of different cations (Mg2+, Na+, K+, Ca2+, and Fe3+) and anions (CO32â, Clâ, PO43â, SO42â, and NO3â) with their different concentrations to simulate the field condition. The experimental results indicated that Ca2+, Mg2+, and Fe3+ have a synergistic effect on removal efficiency of As(V), whereas PO43â and CO32â ions have a significant antagonistic impact. Overall, the order of inhibiting effect of coexisting anions on adsorption of As(V) was arrived as NO3-ËCl-Palavras-chave
