Description The adsorption capacity and selectivity are vital for designing economically feasible treatment system for
drinking water. This work is aimed at enhancing the selectivity of nitrate adsorption through metal
impregnation. Impregnation of Mg, Fe, Co, Ni, Zn and Cu on alumina was investigated. Nickel
impregnation was found to be the best, with an increase in 13 times the nitrate adsorption capacity
compared to unmodified alumina. The optimal pH for nitrate adsorption using nickel-modified alumina
was in a wide range from 3 to 7. The nitrate adsorption capacity was not influenced by the presence of
fluorides and phosphates, whereas carbonates and sulphates were found to decrease the adsorption
capacity by 50%. The adsorbents were also tested on drinking water samples from Madhya Pradesh, India.
The nitrate adsorption capacity of nickel-impregnated alumina was still 10 times higher compared to the
bare adsorbent.
