- W67126919 abstract "The sonolytic decomposition of NHCs(Nitrogen Heterocyclic Compounds), such as atrazine[6-chloro-N-ethyl-N'-(1-methylethyl)-1,3,5-triazine-2,4-diamine], simazine(6-chloro-N,N'-diethyl-1,3,5-triazine-2,4-diamine), trietazine(6-chloro-N,N,N'-triethyl-1,3, 5-triazine-2,4-diamine), in water was investigated at a ultrasound frequency of 200kHz with an acoustic intensity of 200W under argon and air atmospheres. The concentration of NHCs decreased with irradiation, indicating pseudo-first-order kinetics. The rates were in the range <TEX>$1.06{sim}2.07({times}10^{-2}min^{-1})$</TEX> under air and <TEX>$1.30{sim}2.59({times}10^{-2}min^{-1})$</TEX> under argon at a concentration of <TEX>$200{mu}M$</TEX> of NHCs. The rate of hydroxyl radicals(<TEX>${bullet}{OH}$</TEX>) formation from water is <TEX>$19.8{mu}M;min^{-1}$</TEX> under argon and <TEX>$14.7{mu}M;min^{-1}$</TEX> under air in the same sonolysis conditions. The sonolysis of NHCs is effectively inhibited, but not completely, by the addition of t-BuOH(2-methyl-2-propanol), which is known to be an efficient <TEX>${bullet}{OH}$</TEX> radical scavenger in aqueous sonolysis. This suggests that the main decomposition of NHCs proceeds via reaction with <TEX>${bullet}{OH}$</TEX> radical; a thermal reaction also occurs, although its contribution is small. The addition of appropriate amounts of Fenton's reagent <TEX>$[Fe^{2+}]$</TEX> accelerates the decomposition. This is probably due to the regeneration of <TEX>${bullet}{OH}$</TEX> radicals from hydrogen peroxide, which would be formed from recombination of <TEX>${bullet}{OH}$</TEX> radicals and which may contribute a little to the decomposition." @default.
