对广泛使用的除草剂麦草畏（3,6-二氯-2-甲氧基苯甲酸）的辐射分解降解进行了研究，在实验室批量条件下采用 7 辐照并在流通装置中使用加速电子束。研究了剂量大小、辐照溶液中的臭氧或过氧化氢以及硝酸盐和碳酸氢盐等清除剂对麦草畏分解效率和形成产物的影响。通过 Microtox 和 Spirotox 毒性测试测量辐照溶液的毒性变化。还研究了辐射分解降解在商业农用化学品制剂中除草剂分解中的应用。
The radiolytic degradation of the widely used herbicide dicamba (3,6-dichloro-2-methoxybenzoic acid), employing 7 irradiation in laboratory batch conditions and with a beam of accelerated electrons in flow-through installation, was investigated. The effects of dose magnitude, ozone or hydrogen peroxide in irradiated solution, and scavengers such as nitrate and hydrogen carbonate on the effectiveness of dicamba decomposition and the products formed were investigated. Changes in the toxicity of irradiated solutions were measured with the Microtox and Spirotox toxicity tests. The application of radiolytic degradation was also examined for decomposition of herbicides in commercial agrochemical preparations.
