Abstract

Study on using ascorbic acid and ferrous reduction method to removal the chlorate ions (ClO3-) in the water. The results show that 100 mL 3.06 mg/L of ClO3- in ascorbic acid and ClO3- quality ratio 7.19, pH =6.2,35°C, the reaction time of for 15 min, the removal rate was 100%. And ferrous reduction method to remove 100mL 3.06 mg/L of ClO3- in pH = 6.2, Fe2+ and ClO3- quality ratio 1.79, 30℃ for 30min, the removal rate was 51%.

Keywords: Ascorbic acid, ferrous ion, chlorate ions.
