Abstract
In the present paper we have focussed on some different adsorbents for arsenic removal from aqueous media. Adsorbents were divided categorically in two different classes viz., synthetic adsorbents and natural adsorbents. Some of the synthetic adsorbents are found to be good for As(III) and some are good for As(V) removal. Similar results were also obtained for the natural adsorbents although removal efficiency depends on a number of factors. The efficiency of the adsorbents, merits and demerits were discussed in detail. Finally, we have discussed on some patented technologies and some potential filters.
Keywords: Synthetic adsorbents, natural adsorbents, arsenic, adsorption, isotherm, adsorption capacity, column study, regeneration, patent
