Photodegradation study of some triazine-type herbicides

Degradation of atrazine by microwave-assisted electrodeless discharge mercury lamp in aqueous solution

“…However, they are demanding preparation of catalyst and feasible regeneration of catalyst, thus, it is sometimes not desirable. Additionally, atrazine is toxic for microorganisms and the triazine-ring itself is quite resistant to the microbial attack [16]. As a result, conventional biological remediation processes are not efficient and unsuitable to remove higher concentration of atrazine from contaminated water rapidly.…”

Complexation of iron by salicylic acid and its effect on atrazine photodegradation in aqueous solution

“…Fe III ðOHÞ 2þ (9) However, the coexistence of SA and Fe(III) in the aqueous solution delayed the photodegradation rate of atrazine compared to that of iron or SA solution, which can be attributed to the complex interaction between SA and Fe (III). The results of FTIR and UV-visible revealed that SA formed stable complexes with Fe(III).…”

“…Atrazine is toxic for microorganisms and the triazine-ring itself is quite resistant to the microbial attack [9], it is therefore essential to study the photochemical process of atrazine. Iron, a ubiquitous element in natural water, is involved in many photochemical reactions, including those with hydrogen peroxide, organic matters, and trace metals [10].…”

Effects of Pesticides on Marine Bivalves: What Do We Know and What Do We Need to Know?

“…-1 , Giacomazzi and Cochet, 2004). Different compounds including herbicides and their metabolites (Lanyi & Dinya, 2003;Sorensen et al, 2003;Vargha et al, 2005) are detected simultaneously in aquatic environments, suggesting that experimental approaches with toxicant mixtures are needed. Studies with diuron and its metabolites have shown additive, enhanced, antagonistic or independent effects (Knauert et al, 2008;Pesce et al, 2010;Neuwoehner et al, 2010).…”
