    Rates of Reduction of N-Chlorinated Peptides by Sulfite:  Relevance to Incomplete Dechlorination of Wastewaters
    摘要:
    Biologically induced fragmentation of proteins during wastewater treatment produces peptides, which form long-lasting organic chloramines when the water is disinfected with Cl-2. To protect aquatic wildlife from residual chlorine, including chloramines, wastewaters are often treated with sulfur dioxide or sulfite salts. This strategy incompletely eliminates residual chlorine species. Here we report that dechlorination rate constants of N-chloropeptides are 1-2 order of magnitude smaller than those for NH2Cl and some aliphatic organic chloramines. Slow rates explain the prevalence of N-chloropeptides in dechlorinated wastewaters after faster reacting chlorine species have been eliminated. Dechlorination is subject to general acid catalysis. For N-chlorinated leucylalanine, the rate law above pH 6 in phosphate buffer at 25 degrees C and I approximate to 0.1 M is as follows: rate = (9.92 +/- 0.41 x 10(3)[H2PO4-] + 5.70 +/- 0.52 x 10(8)[H3O+] + 5.3 +/- 0.2)[SO32-][Cl-Leu-Ala] (concentrations in M, time in s). Rate constants for other peptides appear to be of similar magnitude; variations in the acid-catalyzed terms among different hydrophobic peptides correlate with solvation energies of side chains. The kinetic data suggest that reducing N-chloropeptides in wastewaters by 75% or more will require reaction times generally >0.5 h at environmentally acceptable S-IV doses and pH values.

  • Kinetics of extremely fast ligand-exchange reactions with methylmercury(II)-nitrothiophenolate complexes: rate-equilibria correlations
    作者:Gerhard Geier、Hugo Gross

    S-donors can also initiate directly the ligand-exchange reactions. The rate constants for the thiophenols are always smaller than those for the thiophenolates. The reactivity of the protonated S-donors is strongly dependent on the nature of the ligand to be displaced. Several features of the reaction mechanisms involved and their relevance for the transport of CH3Hg(II) in natural systems are discussed.
    CH 3 Hg(II)从两种硝基硫代酚盐(4-硝基-2-磺基-硫代苯酚盐和4-硝基-3-羧甲基-硫代苯酚盐)转移到多种其他配体的动力学,并且已经进行了逆反应通过跳温和停流方法进行了研究。在整个平衡常数范围内,即使在等电区域,交换反应也几乎受扩散控制。质子化的S-供体也可以直接引发配体交换反应。硫酚的速率常数始终小于硫酚盐的速率常数。质子化的S-给体的反应性在很大程度上取决于要置换的配体的性质。涉及的反应机理的几个特征及其与CH 3的运输相关性讨论了自然系统中的Hg(II)。

    calculations show possible structures for the intermediates. The reaction between Br(-) and O(3) is accelerated by H(+) but exhibits a kinetic saturation effect as the acidity increases. The kinetics indicate formation of BrOOO(-) as a steady-state intermediate with an acid-assisted step to give BrOH and O(2). Temperature dependencies of the reactions of Br(-) and HSO(3)(-) with O(3) in acidic solutions are
