The Efficiency of Amberjet 4200 Resin in Removing Nitrate in the Presence of Competitive Anions from Shiraz Drinking Water

M. Dehghani, A. Binaee Haghighi and Z. Zamanian    

Abstract: The aim of this research is to study the feasibility of removing nitrates from water by means of anion exchange. In the purposed work an attempt was made to utilize strong basic anion resin to remove nitrate in the presence of competitive anion. Amberjet Cl¯ 4200 ion exchange resin was used in a batch scale. The fixation rate of nitrate without the presences of any competitive anion was almost constant (94.60-96.43) when the nitrate concentrations are in the range of 100-150 mg L-1. The fixation rate of nitrate in the presences of two competitive anions (sulphate and chloride) was reduced to 82% when the concentration of nitrate was 100 mg L-1.
