摘 要:
研究纳米氧化锌对三种有机磷农药的降解情况，考查了催化剂及其用量、光照时间、pH值的影响，结果表明纳米氧化锌能使有机磷农药发生降解。实验结果还表明不同形貌的氧化锌在降解有机磷农药时其效果不一样，网状比粒状所需要时间要短，这可能因为网状的粒径比较小，与降解体系接触空间更大。[著者文摘]

Abstract:
It is studied that three organophosphomus pesticides （parathion, parathion- methyl, carbophenothion） were degraged by nano ZnO of different shapes, and studying the effect of the catalyst and the amount, the time of illumination and pH . The result shows nano ZnO can degrade organophosphorous pesticides with different time, and different shapes of ZnO have different effects. Time of netlike shape degradation is less than graininess shape, possibly because of smaller diameter of net shape, which has much more space to touch the degradation system.[著者文摘]
