Sorption of arsenate using modified natural zeolite by a new bolaform N, N, N, N΄, N΄, N΄-heaxmetheyl-1, 9-nonanediammonium dibromide reagent

In the present study, the feasibility of using modified natural zeolite for arsenate (As(V)) removal from water was evaluated. A new synthetic bolaform, N, N, N, N΄, N΄, N΄-heaxmetheyl-1, 9-nonanediammonium dibromide was employed for zeolite modification. Batch laboratory experiments were carried out to investigate the adsorption capacity of the adsorbent and the removal kinetics of arsenate under different pH values. The maximum removal of As(V) occurred 3.5
