摘要

采用电子束辐照处理盐酸克伦特罗，应用液相色谱串联质谱、红外光谱等技术研究盐酸克伦特罗辐照降解规律及辐解产物的结构，分析辐照对盐酸克伦特罗的降解效应。实验结果表明，原始浓度为18 mg?kg–1和45 mg?kg–1的盐酸克伦特罗水溶液浓度随吸收剂量增加而降低，且在吸收剂量为5 kGy和10 kGy时降解率达到90%以上；在低剂量下(≤5 kGy)盐酸克伦特罗分子的−OH和−Cl基团脱落，随着剂量的增加−OH, −NH2, −NH−和−C(CH3)3等基团也发生了不同程度的改变或脱落，表明电子束辐照可有效降解盐酸克伦特罗。

Abstract

The degradation effect of electron beam irradiation on clenbuterol hydrochloride was investigated with the method of liquid chromatography-tandem mass spectrometry and infrared spectroscopy. Experimental results showed that the concentration of clenbuterol hydrochloride aqueous solution with original level of 18 ppm and 45ppm decreased with the increase of absorbed dose, and its degradation efficiency was higher than 90% at 5 kGy and 9 kGy respectively. The mass spectrometry showed that −OH and −Cl fell off at low absorbed dose. And with the increase of absorbed dose, the ions such as −NH2, −NH−, −C(CH3)3, −Cl were changed or lost. It indicates that electron beam irradiation could efficiently degrade clenbuterol hydrochloride.Cited
