| 摘 要： | 采用不同剂量(0、3、6、9、12、15 kGy)60Co-γ射线对柄曲霉素(sterigmatocystin,STC)溶液进行辐照处理,研究辐照剂量、不同溶剂以及不同初始浓度对柄曲霉素辐照降解效果的影响。结果表明:60Co-γ射线可有效降解溶液中的柄曲霉素,且降解率随着辐照剂量的增大而增加。当辐照剂量为3 kGy时,STC的降解速率依次为水>氯仿>乙腈>甲醇。当辐射剂量大于6 kGy时,水、乙腈和氯仿中STC的降解率相近,且甲醇中STC降解率也相对增加。在同一辐照剂量下,柄曲霉素的初始浓度越低,其降解率越高。

| Abstract: | In this study,the solutions of sterigmatocystin(STC)were irradiated by different doses(0,3,6,9,12,15 kGy)60Co-γray radiation.The effects of irradiation dose,different solvents,initial concentrations on STC were investigated.The results showed that STC could be effectively degraded by 60Co-γray and the degradation rate increased with the increase of irradiation dose.The STC degradation rate was in the order of water>chloroform>acetonitrile>methanol when the irradiation dose was 3 kGy.Degradation rate in methanol was increased relatively and similar in water,acetonitrile and chloroform at the irradiation dose of greater than 6 kGy.At the same irradiation dose,the degradation rate was higher along with lower initial concentrations of STC. |
