摘要:
应用3、5、10 MeV电子束能量和0.6、1.06、1.92、2.62、3.33、4.09、5.1、9.4、13.84、21.68 kGy共10个不同辐照剂量下,对恩诺沙星化合物的辐照降解研究,分析不同电子束能量和辐照剂量对化合物降解率的影响.结果表明,电子束能量对少量恩诺沙星样品的降解率基本没有影响;当辐照剂量为1.06 kGy时,恩诺沙星降解率已达93%;10 MeV的电子束能处理含恩诺沙星水样的最佳厚度为120 mm,辐照降解率不低于94%.由此可见,电子束辐照是有效降解恩诺沙星难降解化合物的技术方法,并适合大规模推广应用.

Abstract:
Irradiation degradation of enrofloxacin was carried out with different electron energies under different irradiation doses, which included 0.6, 1.06, 1.92, 2.62, 3.33, 4.09, 5.1, 9.4, 13.84, 21.68 kGy. The electron energies were 3 MeV, 5 MeV and 10 MeV, respectively. The results indicated that the electron energy has no influence on the degradation rate of enrofloxacin. When the irradiation dose was 1.06 kGy, the degradation rate of enrofloxacin already reached 93%. The optimum thickness on the irradiation degradation of enrofloxacin for 10 MeV of electron beam energy was 120 mm with a degradation rate of 94%. Therefore, the electron beam irradiation can be used to degradate enrofloxacin effectively, which is a technique and suitable for large scale application.
