The chloramine-T-Phenol Red procedure affords a potentially very sensitive photometric method for the determination of bromide. However, serious problems (poor precision and high reagent blanks) have been encountered in trials which followed exactly the published procedure. The reason for these difficulties was found to be the high ratio of chloramine-T to Phenol Red which was used. In all prev...
Chloramine (which occurs widely as a by-product of sanitary chlorination of water supplies) is shown to be a weak mutagen, when reversion of trpC to trpC in Bacillus subtilis is used as an assay. Some DNA-repair mutants appear to be more sensitive to chloramine, suggesting the involvement of DNA targets in bactericide. The influence of plating media on survival of cells treated with chloramine ...
Objectives: (State the relevant objectives of the project; 75 words or less.) This study was designed to contribute to a better understanding of the fate of chloramines in distribution systems. The project objectives were to: 1) characterize the influence of water quality parameters on chloramine decomposition rates; 2) evaluate and compare chloramine decomposition rates in distributions system...
The complex [Tpm(*,Br)Cu(NCMe)]BF4 (Tpm(*,Br) = HC(3,5-Me2-4-Br-pyrazolyl)3) catalyses the aziridination of alkenes and the amidation of cyclic ethers with chloramine-T as the nitrene source and the ionic liquid [bmim]PF6 as the reaction medium (bmim = 1-n-butyl-3-methylimidazolium). High conversions have been obtained over several cycles of catalyst recovery and reuse.
Arthur, J. and J. Eaton (1971). "CHLORAMINE TOXICITY TO THE AMPHIPOD GAMMARUS PSEUDOLIMNAEUS AND THE FATHEAD MINNOW(PIMEPHALES PROMELAS)." amphipods (gammarus pseudolimnaeus) were subjected to 96 hr and 15 week exposures, and fathead minnows (pimephales promelas) to a 21 week exposure of various chloramine concentrations under continuous flow conditions. The most marked sublethal effects were r...
