Infrared study of chlorophenols and products of their photodegradation.
The presents study of the 3-chlorophenol, 2,4-dichlorophenol, 2,3,4,5-tetrachlorophenol, pentachlorophenol and products of their photodegradation using FT-IR spectroscopy and GC/MS. Spectra of pure chlorophenols with the spectra of their solutions after photodegradation were compared. FT-IR spectra of pure chlorophenols investigated in the region of 3700-3000cm(-1) show that in particular cases the position and shape of bands corresponding to stretching vibration of hydroxyl groups are different. In all cases, the differences between spectra of pure chlorophenols and irradiated solutions were observed. It was confirmed that different distribution of types of hydrogen bonds appearing in particular chlorophenols has strong influence on the process of irradiation reaction and final products.
