摘要

抗坏血酸-亚铁还原法去除水中氯酸盐离子的研究。结果表明,100 mL中3.06 mg/L的clo3 -与抗坏血酸中clo3 -的质量比为7.19,pH =6.2,35℃,反应时间为15 min,去除率为100%。而亚铁还原法在pH = 6.2、fe2 +与clo3 -质量比为1.79、30℃作用30min的条件下去除100mL 3.06 mg/L的clo3 -,去除率为51%。

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