AB  - Nicosulfuron, a sulfonylurea herbicide, was subjected to different Fenton reactions at pH of a nicosulfuron aqueous solution (pH 5). Usually, the optimal pH for the Fenton reaction is between 3 and 4, but the addition of acids is not environmentally acceptable. This is the reason why the reactions were performed at a higher pH value than usual. So, classical Fenton and Fenton-like reactions were applied as well as phot-Fenton and photo-Fenton-like reactions. In addition, microwave Fenton and Fenton-like reactions were used in nicosulfuron degradation. Influences of Fe2+ and Fe3+ concentrations, as well as hydrogen peroxide concentrations, were studied The Fenton reaction was much faster and more efficient than the Fenton-like reaction, while the photo-Fenton reaction proceeded much faster and more efficiently than the Fenton reaction. The microwave-Fenton and microwave-Fenton-like reactions proceeded with increased efficiency in comparison to the Fenton and Fenton-like reactions. The phytotoxicity and acute toxicity of the reaction products of nicosulfuron oxidation by the photo-Fenton reaction were analyzed The toxicity testing of nicosulfuron treatment by photo-Fenton process showed a decrease in phytotoxicity, while the acute toxicity tests showed that the samples after treatment had lower toxicity.

AB  - In the present study, the photocatalytic degradation of nicosulfuron, using TiO2 as a catalyst under UV light (315-400 nm), was studied. The optimization of the nicosulfuron photodegradation was performed. It was found that the optimal concentration of the catalyst was 1 g L-1 at concentration of nicosulfuron solution of 20 mg L-1 while the highest reaction rate was obtained using 2 g L-1. The degradation rate was the highest at pH .= 5.0. Effects of anions (Cl-, SO42- NO3- and F-) and cations (Na+, Ca2+, Al3+) were investigated. In addition, the influence of isopropanol, acetone, and hydrogen peroxide was studied. It was shown that the photocatalytic degradation is mainly due to the reaction of nicosulfuron with (OH)-O-center dot in solution. Also, liquid chromatography coupled with mass spectrometry (HPLC-MS) was used to identify intermediates during the photocatalytic degradation of nicosulfuron. the mineralization was monitored with ion chromatography (IC) and total organic carbon (TOC) analysis. Although 100% HPLC removal of nicosulfuron was achieved, only 69% TOC removal after 90 min was recorded. The results of ion chromatography showed that the mineralization resulted in ammonium and nitrate ions during the process. The phytotoxicity experiments using mung bean seeds showed a reduction in phytotoxicity.

AB  - The study of photodegradation of dimethenamid-P herbicide was performed in deionised and ground water using TiO2 as a catalyst under UV light. The effect of electron acceptor (H2O2), scavenger of (OH)-O-center dot radicals (C2H5OH) and scavenger of holes (NaCl and Na2SO4) as well as solution pH was analyzed. The photodegradation of dimethenamid-P was followed by HPLC. The formation of transformation products was followed using high performance liquid chromatography-electrospray mass spectrometry. Ion chromatography and total organic carbon measurements were used for the determination of the mineralization level. HPLC analysis showed the almost complete removal of herbicide after 90 min in deionised and ground water, while total organic carbon analysis showed that dimethenamid-P was mineralized 64 and 50% in deionised and ground water, respectively. The ion chromatography results showed that the mineralization process leads to the formation of chloride, sulphate and nitrate anions during the process. Transformation products were identified and the degradation mechanism was proposed.

AB  - For the first time the electrochemical degradation of the pesticide dimethenamid-P was studied. Its direct electrochemical degradation, using potential cycling at a gold electrode, was performed by cyclic voltammetry and HPLC analysis of electrolyte after 72 h showed 56.8% of degradation. HPLC-MS indicates the formation of degradation products through the elimination of chlorine atom and C-N bond cleavage. By indirect electrolysis using DSA Ti/PtOx and DSA Ti/RuO2 electrodes during 30 minutes 87.2% and 88.3% of dimethenamid-P was degradated, respectively. The high percentage of degradation of dimethenamid-P was achieved with non time consuming, simple and cheap electrochemical processes.
