Adsorptive removal of water poisons such as Pb(II), Cu(II), Mn(II), Hg(II), CN−, microbes, nerve and blister agents (concentration range from 100 to 1000 mg/L) were studied by using adsorbents such as active carbon, impregnated carbon and bentonite loaded fabric strip. Removal of water poisons (99.5 % ) could be achieved with an optimum stirring time of 5–15 min and weight of adsorbent of 0.8–8.0 g/100 mL contaminated water, respectively. However, 85 % bentonite loading was found to be most effective for Pb(II) removal. Effect of contaminants concentration was also studied.
