The decomposition of benzo[a]pyrene (BAP), chrysene (CHR) and fluorene (FLU) in an aqueous solution by means of photolysis has been studied. The influence of initial polycyclic aromatic hydrocarbons' (PAHs) concentration, pH of the reaction mixture, temperature, presence of oxygen and tert-butyl alcohol (t-BuOH) on the degradation rate has been observed. BAP and CHR are decomposed by a mechanism different than FLU. Quantum yields of the photolytic decomposition of BAP, CHR and FLU were determined and equal 0.014, 0.0031 and 0.0038, respectively.
研究了通过光解作用使水溶液中的苯并[a]芘（BAP）、屈（CHR）和芴（FLU）发生分解的情况。观察了初始多环芳烃（PAHs）浓度、反应混合物的pH值、温度、氧气的存在以及叔丁醇（t-BuOH）对降解速率的影响。BAP和CHR的分解机制与FLU不同。测定了BAP、CHR和FLU光解分解的量子产率，分别为0.014、0.0031和0.0038。
