研究了环糊精衍生物甲基化-β-环糊精(MCD)和羟丙基-β-环糊精(HPCD)对甲基对硫磷的紫外光降解的影响,结果表明:MCD或HPCD与甲基对硫磷混合光照后,甲基对硫磷的光解速度加速了4.87～6.85倍,表现了较强的光敏效应,其敏化效率随光照时间延长而提高,且与MCD和HPCD浓度及光照时间均呈正相关.

The effects of methylβcyclodextrin and hydropropylβcyclodextrin on photodegradation of parathionmethyl were investigated.The result showed the photolytic rates of parathionmethyl were increased to 4.87～6.85 times with methylβcyclodextrin or hydropropylβcyclodextrin,a positive correlation was observed between photosensive efficiency and irradiation time and the concentration of methylβcyclodextrin an...
