摘要

本文采用0—10 kGy的,60,Co γ射线对水溶液中的磺胺二甲基嘧啶、噁喹酸、氯霉素、呋喃唑酮、土霉素进行处理，并测定了环境的酸碱性、空气、温度对辐照降解率的影响。结果表明，,60,Co γ射线辐照处理能显著降解五种常见渔药在水中的残留，吸收剂量越大，渔药的降解率越高；初始浓度越低，越有利于渔药的去除。当吸收剂量为8 kGy时，五种渔药（初始浓度100 mg/L）的降解率均达到90%以上，酸碱性和空气环境对不同种类的渔药降解率影响有一定的差异，降低温度对渔药降解有明显抑制作用。

Abstract

The degradation of five kinds of fishery drugs in aqueous solution irradiated by ,60,Co γ-rays at the absorbed dose of 0—10 kGy was investigated. The effects of acid/base, degassing and temperature on the degradation of fishery drugs were studied. The results show that fishery drugs can be degraded significantly with ,60,Co γ-rays irradiation, and the higher absorbed dose the higher degradation efficiency. The degradation percentage increases with the decrement of initial concentration of fishery drugs. More than 90% degradation of five fishery drugs has been achieved at absorbed dose of 8 kGy. The effects of acid/base and degassing environments on the degradation of fishery drugs are different. The lower temperature can inhibit remarkably the degradation of fishery drugs in aqueous solution.
