Fate of herbicide-derived aniline residues during ensilage

Photocatalytic oxidation of aniline using Ag+-loaded TiO2 suspensions

“…This result suggests that the CO 3 À reacts with aniline more efficiently to yield anilino radical cation, which then produces azobenzene, as per Eqs. (13) and (14). The activity of the used catalysts for the photodecomposition of aniline decreases gradually with increasing irradiation (Fig.…”

“…Aniline is also found in the effluents of coal liquefaction [13]. A large number of methods including biological [14][15][16], chemical [17,18] and photochemical ones [19][20][21][22][23][24] have been used for the removal of this pollutant. Biological methods are often sensitive to temperature and surrounding conditions and also have the limitation of being slow.…”

Oxidation of aniline and other primary aromatic amines by manganese dioxide

“…Along with phenol, aniline is listed as a high-priority compound in the study of pollutants from coal-conversion process wastes (5). Aniline residues are formed in the soil as a result of microbial and plant metabolism of phenylurea, acylanilide, phenylcarbamate, and nitroaniline herbicides (6). Chlorinated anilines such as 2,4,5-trichloroaniline, 4-chloroaniline, 3,4-dichloroaniline, and 2,6-diethylaniline may be released as degradation products and intermediates of various phenylurea and phenylcarbamate pesticides (7,36).…”

“…Aniline and other aromatic amines are subject to complex environmental transformations. Lyons, Katz, and Bartha (6,10,11) performed studies on the microbial pathways for aniline elimination from aquatic environments, from which they concluded that biodegradation may be the most significant mechanism for the removal of aniline from pond water. Hwang and Lee (7) concluded that photochemical processes were primarily responsible for mineralization of 2,4,5-trichloroaniline in surface water 0013-936X/90/0924-0363$02.50/0 © 1990 American Chemical Society Environ.…”

Degradation of Aniline by Delftia tsuruhatensis 14S in Batch and Continuous Processes

“…According to mass spectrometry, these compounds had M + values of 135 and 121, and their fragmentation patterns corresponded to acetanilide and formanilide. These compounds are known as products of the detoxification process widely occurring among microorganisms [18]. At aniline concentrations above 1400 mg/l, biomass growth was nonlinearly dependent on aniline consumption.…”
