摘要：

为了利用光催化降解剂降低甚至消除农产品的农药残留，解决食品安全问题。本研究以水果中的有机磷农药残留为研究对象，探索了纳米TiO2粉体和水凝胶对苹果和洋李中毒死蜱残留的光催化降解效果。结果表明：二者均能很好的降解苹果和洋李中的毒死蜱残留，TiO2水凝胶的光催化效果稍优于纳米TiO2粉体。纳米TiO2本身无毒，光催化活性高，作为光催化降解剂在降低或消除农产品中的有机磷农药残留这一领域具有广阔的发展前景。

Abstract:

Pesticide residuals in agricultural products threaten human health. A new solution to this problem was to use potocatalytic degradation agent to degenerate these residuals. This paper explored the photocatalytic effects of nanometer TiO2 both in powder and hydrogel forms in degenerating chlorpyrifos residual in apples and damsons. The results showed that both powder and hydrogel forms work well. However, Hydrogel form was more effective than powder form. Because it was innoxious and highly photo catalytic, TiO2 has broad development prospects as a photocatapytic degradation agent to degenerate pesticide residuals in agricultural products.
