【摘要】 本文采用0～10kGy的⁶⁰Co-γ射线辐照方法,对五种渔药进行了系统的降解试验,分别考察了渔药种类、吸收剂量、初始浓度、酸碱性、脱气、温度对五种药物辐照降解效果的影响。结果表明⁶⁰Co-γ射线辐照处理对五种渔药降解效果都比较显著,并且吸收剂量越大,药物的降解率越高,初始浓度越低,越有利于药残的去除,酸碱性、脱气处理对不同种类的药物降解率影响不相同,低温处理可以明显抑制药物降解。更多还原

【Abstract】 Degradation of five kinds of fishery drugs in aqueous solution was detected by ⁶⁰Co-γradiation with the dose of 0～10kGy.Efficiencies of fishery drugs degradation were evaluated with different kind,absorbed dose initial concentrations,acid/base properties,degassing and temperature.The results showed that ⁶⁰Co-γray radiation has remarkable effect on the degradation of fishery drugs.The degradation efficiency enhanced with increased irradiation doses and reduced concentrations.The degradation efficiency of different drugs in acid/base properties and degassing environments is different.Low temperature can absolutely inhibit the degradation in aqueous solution.更多还原
