本工作采用流化床反应器,配合超声波萃取和索氏提取,借助于GC和GC/MS研究了菲涂在颗粒物上与O_2和NO_2的光化学反应,分析测定了反应的动力学和反应产物,并用Ames试验测定了反应产物的致突变性。 文章第一部分研究了菲涂在硅胶上与O_2的反应,结果表明,菲在硅胶上不与O_2发 In this work, the fluidized bed reactor was used in combination with ultrasonic extraction and Soxhlet extraction, and the photochemical reaction of TiO 2 with O 2 and NO 2 was studied by means of GC and GC / MS. The reaction kinetics and reaction products were analyzed. Ames test was used to determine the mutagenicity of the reaction product. The first part of the paper studied the reaction of phenanthrene on silica gel with O 2. The results show that phenanthrene does not react with O 2 on silica gel
