Abstract | Laboratory studies on arsenic removal were carried out to compare coagulation with ferric chloride and adsorption onto preformed hydrous ferric oxide. Adsorption was found to be an important (though not the sole) mechanism governing arsenic removal during coagulation. Better removal was observed with arsenic (V) [As(V)] than with arsenic (III) [As(III)] in both coagulation and adsorption. The effect of variations in pH and in the presence of sulphate was investigated. |
