Iron(III)-photoinduced degradation of 4-chloroaniline in aqueous solution
Original language description
The degradation of a prototypical halogenoaromatic pollutant, 4-chloroaniline (4-CA), photoinduced by Fe(111) species, has been studied in acidic aqueous solutions (pH 2-4) of Fe(ClO4)(3) by means of product analysis and nanosecond transient absorption spectroscopy. The degradation process is initiated by the attack of OH radicals on 4-CA, leading to radical cations, 4-CA(.+) as the major transient species. At high photon fluences, the decay of 4-CA(.+) is dominated by second-order reactions; an accelerating effect of Fe(111) could be evidenced at low fluence. A large number of minor reaction intermediates could be detected by product analysis following continuous irradiation at lambda(exc) = 365 nm of aerated solutions, arising from ring substitution,ring opening and oligomerization processes. At higher concentration of 4-CA, the specificity of the degradation process increases; the oligomerization pathway becomes predominant and leads to three major oligomeric products, one of which
