Among these complexes, the mer-[FeCl<sub>3<\/sub>(terpy)] complex showed the highest catalytic activity for the oxidative degradation of 2,4,6-tribromophenol (TrBP) using KHSO<sub>5<\/sub> as an oxygen donor. The turnover numbers for the degradation and debromination of TrBP in the mer-[FeCl<sub>3<\/sub>(terpy)]\/KHSO<sub>5<\/sub> catalytic system were estimated to be 1890 \u00b1 1 and 4020 \u00b1 216, resp. The catalytic activity was significantly inhibited at pH 4-7 in the presence of a humic acid, a major component of landfill leachates. However, the percent of TrBP degradation and debromination increased at pH 8. GC\/MS analyses showed that a major oxidation product was 2,6-dibromo-p-benzoquinone (DBQ) and its level decreased with increasing reaction time, suggesting that organic acids (identified by LC\/TOF-MS) are formed via the ring-cleavage of DBQ. Mineralization to CO<sub>2<\/sub> was observed to be 15% as a result of the oxidation for a 3 h period, where TOC values before and after the reaction were measured. Absorption spectra of mer-[FeCl<sub>3<\/sub>(terpy)] with m-chloroperoxybenzoic acids as an oxygen donor in acetonitrile showed that a center metal, Fe, formed a peroxide complex with the oxygen donor.<\/p>\n<p>Journal of Molecular Catalysis A: Chemical published new progress about 930-36-9. 930-36-9 belongs to pyrazoles-derivatives, auxiliary class Pyrazole, name is 1-Methylpyrazole, and the molecular formula is C4H6N2, <a href=\"https:\/\/www.ambeed.com\/products\/930-36-9.html\">Recommanded Product: 1-Methylpyrazole<\/a>.<\/p>\n<p>Referemce:<br \/><a href=\"https:\/\/en.wikipedia.org\/wiki\/Pyrazole\">https:\/\/en.wikipedia.org\/wiki\/Pyrazole<\/a>,<br \/><a href=\"Pyrazole - Wikipedia\">Pyrazoles &#8211;
