RUI: Halogenation of Model Compounds of the Humic Acids: Investigation of Contaminant Formation During Drinking Water Treatment

这项工作的目的是调查饮用水污染物的形成。 将研究由氯化（在某些情况下是溴化）试剂与腐殖酸和其他有机材料反应形成的化合物。 一些苯酚和间苯二酚相关的腐殖酸模型，这是以前很少受到关注，将氯化和溴化在各种溶剂和反应产物将被确定。 在近中性pH值的水中，活性氯化剂二氯胺与苯酚的反应将被研究。 涉及腐殖酸模型和含有氯氧键的氧化剂的反应也将受到关注。 还将对溴化剂进行类似的研究。有了这个奖项，有机和高分子化学计划是支持博士维克托L。他是Point Loma Nazarene学院化学系的教授。 Heasley博士将探索用氯化剂处理饮用水过程中发生的污染物形成。 天然存在的腐殖酸模型（在所有沃茨中发现的植物材料）将用氯和溴处理，并确定反应产物。 了解这些反应应该提供有关如何实现水净化的信息，同时最大限度地减少这些副产物的形成。 通过RUI（本科院校研究）项目培训的学生将获得环境化学和有机化学方面的经验。 这些本科生通常继续在制药或特种化学工业工作，或继续在研究生院或医学院深造。

The objective of this work is to investigate the formation of drinking water contaminants. Compounds which are formed by the reaction of chlorinating (and in some cases brominating) agents with humic acids and other organic materials will be studied. A number of phenol and resorcinol related humic acid models, which have received little attention previously, will be chlorinated and brominated in a variety of solvents and the reaction products will be identified. Reactions of dichloramine, the active chlorinating agent at near neutral pH in water, with phenols will be studied. Reactions involving humic acid models and oxidants containing chlorine-oxygen bonds will also receive attention. Similar studies with brominating agents will also be performed. With this award, the Organic and Macromolecular Chemistry Program is supporting the research of Dr. Victor L. Heasley of the Department of Chemistry at Point Loma Nazarene College. Dr. Heasley will explore contaminant formation which occurs during the treatment of drinking water with chlorinating agents. Models of naturally occurring humic acids (plant material found in all waters) will be treated with chlorine and bromine and the reaction products determined. Understanding these reactions should provide information about how water purification can be accomplished in conjunction with minimizing the amount of these byproducts formed. Students trained as a result of working on this RUI (Research in Undergraduate Institutions) project will gain experience in environmental chemistry as well as organic chemistry. These undergraduate students typically go on to work in the pharmaceutical or specialty chemical industries or go on to advanced study in graduate or medical schools.
