Chloroaromatic pesticides authors point out that photo-oxidants generated by humates appear to be of greater environmental significance than Julliard et al [79] The photodegradation of imazapyr h2-(4-isopropyl-4-acetatej, in an ethanol / water mixture using sodium sulfite methyl-5-oxo-2-imidazolin-2-yl)nicotinic acidj by simuas sacrificial electron-donor. After 7 h of irradiation of lated sunlight was studied at pH 7 in the presence of humic chloroneb, 95% dechlorination was observed, with the acids [191].…”

The photodegradation of pesticides is reviewed, with particular reference to the studies that describe the mechanisms of the processes involved, the nature of reactive intermediates and final products. Potential use of photochemical processes in advanced oxidation methods for water treatment is also discussed. Processes considered include direct photolysis leading to homolysis or heterolysis of the pesticide, photosensitized photodegradation by singlet oxygen and a variety of metal complexes, photolysis in heterogeneous media and degradation by reaction with intermediates generated by photolytic or radiolytic means.

“…Reductive catalytic methods have been also reported, e.g. with Pd/Mg bimetallic particles [18], via electrolytic [19], or photosensitized reductive dechlorination methods [20]. A number of studies on the non-catalytic reductive dechlorination of DDT have been also reported [21], which however do not give complete dechlorination.…”

Selectivity and product distribution of hydrodechlorination (HDCl) of dieldrin and DDT are studied in different liquid phase systems, namely in: (1) in ethanol; and (2) in the supported ionic liquid heterogeneous catalytic system (multiphase system), composed by the organic phase and aqueous KOH, a quaternary ammonium ionic liquid promoter (Aliquat 336), and a metal catalyst, e.g. 5% Pd/C, 5% Pt/C, or RaneyNi. At 50 8C and atmospheric pressure of hydrogen, a quantitative hydrodechlorination of DDT in the biphasic system with ionic liquid layer is achieved in 40 min and in 4 h with Raney-Ni and Pd/C, respectively, while the reaction on Pt/C or on Pd/C without Aliquat 336 is slow. Dieldrin undergoes partial dechlorination, with high selectivity achievable only for its mono-and bi-dechlorination products. Dechlorination pathways and reactivity of different types of organic chlorine atoms versus the catalyst nature and other conditions are discussed. #
