Identification of N-Chloroaldimines in Chlorinated MunicipalWastewater

本项目的目的是确定和量化使用氯对污水处理厂流出物进行消毒时的化学反应产物。本项目特别强调废水中氨基酸和多肽等含氮有机化合物与氯之间的反应。计划将光谱技术用于鉴定氯化产物；在表征其稳定性的过程中，并确定传统的分析方法如何对这些化合物的存在作出反应。在美国，在污水排入环境水域之前，严重依赖氯化消毒。众所周知，氯能与有机化合物反应形成产品，其中许多产品对下游用水者的环境意义尚未得到充分表征。预计该项目的结果将为工程设计和氯化使用中可能需要的任何更改提供基础，以避免或消除与使用该过程相关的环境问题。

The objective of this project are to identify and quantify chemical reaction products when chlorine is used to disinfect wastewater treatment plant effluents. Special emphasis in this project is on reactions between nitrogenous organic compounds such as the amino acids and peptides in the effluents with chlorine. Spectral techniques are planned to be used for identification of the chlorination products, in the process of characterizing their stability and to determine how conventional methods of analysis respond to the presence of these compounds. Chlorination is relied on heavily in the United States for disinfection of effluents prior to their placement in environmental waters. Chlorine is known to react with organic compounds to form products many of which have not been fully characterized with respect to their environmental significance for downstream water users. Results of this project are expected to provide the basis for any changes that may be necessary in engineering design and use of chlorination to avoid or eliminate environmental problems associated with use of this process.
