Granulated inorganic sorbents based on KSKG silica gel and aluminum oxide modified with Fe(III) compounds were developed for water purification from As(V). Physicochemical properties of synthesized sorbents were studied. It was discovered that the dynamic exchange capacity for As(V) varied in the following series: Al₂O₃–7Fe–Amk-290 < SiO₂–7Fe–Az < SiO₂–7Fe–Ox < SiO₂–7Fe–Amk-290 < Si₂–7Fe–Amk-600.
