摘　　要：采用高铁酸钾(K_(2)FeO_(4))去除饮用水中的2-溴乙酰胺(MBAcAm),考察反应时间、K_(2)FeO_(4)投加量、pH以及温度对去除效果的影响。结果表明:MBAcAm的去除率随着反应的进行而逐渐上升;增加K_(2)FeO_(4)的投加量,去除率不断提高,当投加量从0.01 g/L增加到0.10 g/L时,去除率提高了22.75%;pH对去除效果的影响显著,当pH=6时,去除率达到最高值74.44%;温度对去除效果的影响较小。MBAcAm的去除过程符合一级动力学反应规律。Potassium ferrate(K_(2)FeO_(4))was used to remove monobromoacetamide(MBAcAm)in drinking water with investigation of the effects of reaction time,K_(2)FeO_(4)dosage,pH and temperature on the removal effect.The results show that the removal rate gradually increased with the progress of the reaction;increase the dosage of K_(2)FeO_(4),and the removal rate continued to increase,when the dosage was increased from 0.01 g/L to 0.10 g/L,the removal rate increased by 22.75%;pH had a significant influence on the removal effect of MBAcAm,when pH=6,the removal rate reached the highest value of 74.44%;temperature had little effect on MBAcAm removal.The removal reaction of MBAcAm conformed to the first-order kinetic law.
