摘　　要：基于传统水处理方法对水中抗生素处理较困难,研究了Fe2+活化过硫酸钠产生的硫酸根自由基降解水体中红霉素的效果,分别考察了Na2S2O8的用量、Na2S2O8与Fe2+物质的量比、p H值3个因素对降解效果的影响。结果表明,在一定范围内,Na2S2O8的浓度越大,降解率越大;在碱性条件下,降解红霉素的效果较好;当Na2S2O8与Fe2+物质的量比为2∶1时,降解率基本达到最高,而再增大比例,降解率反而降低。Because the traditional water treatment method is more difficult to deal with the antibiotics in water, the degradations of erythromycin in water using sulfate radical generated by ferrous ion-activated sodium persulfate were studied. The effects of Na2S2O8 dosage, initial p H value and molar ratio of Na2S2O8 to Fe^2＋on degradation were investigated.The results show that with the greater concentration of Na2S2O8 in a certain range, the greater the degradation rate is; in alkaline condition, the degradation effect of erythromycin is better; when the molar ratio of Na2S2O8 to Fe^2＋is 2 ∶1,degradation rate is the highest, and instead of increasing the proportion of the degradation the rate is decreased.
