Separation and determination of arsenic species in water by selective exchange and hybrid resins

► A simple and efficient method for separation and determination of arsenic species. ► A new hybrid resin HY-AgCl is effective for iAs and oAs analytical separation. ► SBAE resin was convenient for the separation of As(III) from As(V) and oAs species. ► HY-Fe resin was convenient for the separation of DMAs(V).
