| 摘 要： | 为了降解农药废水,以混晶纳米TiO2乳液为催化剂,以太阳光为光源,对降解农药模拟废水进行了系统研究.结果表明:降解体系的pH值、催化剂和农药质量浓度、光源辐照时间等因素对乳液光催化降解农药有一定影响,反应动力学研究表明此降解反应是一级反应(K=0.014 35 min-1).

| 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)). |
