Experimental Study on Chemical Reduction Method to Remove the ChlorateIons in the Water

Abstract

Study on using ascorbic acid and ferrous reduction method to removal the chlorate ions (ClO 3 - ) in the water. The results show that 100 mL 3.06 mg/L of ClO 3 - in ascorbic acid and ClO 3 - quality ratio 7.19, pH =6.2,35℃, the reaction time of for 15 min, the removal rate was 100%. And ferrous reduction method to remove 100mL 3.06 mg/L of ClO 3 - in pH = 6.2, Fe 2+ and ClO 3 - quality ratio 1.79, 30℃ for 30min, the removal rate was 51%.
