Arsenic removal from water was investigated using activated carbon. The chemical activated carbon (CAC) prepared using H3PO4 from jute stick largely featured micropore structure with surface functional,groups, while meso- and macropore structures were mainly developed in physical activated carbon (PAC). The CAC and PAC reduced arsenic concentration to 45 and 55 mu g L-1, respectively, from 100 mu g L-1 while iron-loaded CAC reduced to 3 mu g L-1, which is lower than the upper permissible limit (10 mu g L-1). The micropore structure of CAC along with complexation affinity of iron species towards arsenic species attributed to enhanced separation of arsenic.
