| Abstract: | Photodegradation of PAHs in aerosols sorbed on quartz filter was detailed observed. The Photodegradation of PAHs was first-order recreation.The photodegradation rate constants (k) and half-lives (t1/2) were determined in ultraviolet light of 253. 7nm. The relation between the photodegradation rate constants and the oxidation-half-wave potential (E1/2) and the structure of PAHs were discussed. |
