Influence of carrier type on arsenic (V) removal by activated carbon-iron (III) oxyhydroxide adsorbents

Abstract

According to EPA, WHO, EU Directive and Ukrainian regulations, at present the maximum acceptable concentration of arsenic in drinking water is 10 μg/l. Whereas in many countries the content of arsenic in natural water can be up to 1000 μg/l or higher, what is significantly higher than the permissible concentration. Four species of activated carbon (birch activated carbon (BAC), coconut activated carbon (CAC), bituminous activated carbon Filtrasorb 300 (F300) and bituminous activated carbon Filtrasorb 400 (F400)) were used for doping to determine the influence of carrier type on As(V) removal by activated carbon-iron (III) oxyhydroxide adsorbents. Carrier effectiveness increased in the sequence BAC-F400-F300-CAC.
