Abstract

α, β and γ cyclodextrin polymers (CDP) has been successfully tested for arsenic (As) removal from As contaminated water. Removal of As (III) was studied through batch adsorption experiment at pH 3.6 to 9.0 with different time ranges from 0.5 to 24 h. α, β and γ−CDP worked well at pH 6.8 but highest As removal (86.9%) was achieved from γ-CDP at pH 5.0 from the 100 µg L^-1 As solution after 24 hours incubation. Considering the time, α-CDP has reached the maximum 86% As removal occurred at pH 6.8 within 30 minutes. But at highly acidic (pH 3.6) and basic medium (pH 9.0), all of these CDP did not performed well for As adsorption. α and β-CDP has the capability to reduce As is less than 20 µg L^-1 at pH 6.8 and only γ-CDP has capable to achieve this limit at pH 5.0, which below the limit of As standard in Bangladesh (50 µg L^-1). So, according to pH of water, this adsorbent might be used in different regions as and where is suitable.
