Ptotocataiytic Degradation of Pesticide Using Mix-crystal TiO_2 Emulsion

doi:10.3969/j.issn.1000-1565.2010.01.011

Abstract

Abstract: In order to degrade the agricultural chemicals waste water. This experiment is based on mixed crystal nano-TiO_2 emulsion as a catalyst and the sunlight as the photo source to degrada the pesticide wastewater. The influence of many parameters such as initial pH, catalyst loading, and initial pesticide mass concentration were also discussed. The plot ln(ρ_0/ρ) to irradiation time was linear, suggesting first order reaction (K＝0.014 35 min~(-1)).

Key words: mix-crystal TiO_2 emulsion, photocatalytic, pesticide degradation
