氨基酸和氨基糖（AAAS）对饮用水处理非常重要， 因为它们可以作为生物活性的底物，可以作为可溶性蛋白质的指示剂 微生物产物，可能是含氮消毒副产物形成的前体。 尽管有这些重要的需求，但几乎没有什么工作可以用来理解 饮用水中的氨基酸。这个项目的目标是测量溶解氨基酸 有机物（DOM）将大量水与饮用水源隔离开来。 从受季节变化影响的水域采集了大量水和DOM样本 藻华或废水排放。从10个全尺寸容器中采集大量水样 2006年夏秋期间全国各地的水处理厂（WTP）。 样品 分析了多种水质，包括:溶解有机碳（DOC）， 紫外线吸收率（UVA）、总溶解氮（TDN）、溶解无机氮 （DIN）和溶解有机氮（DON）。浓缩500毫升（mL）的等分液 冷冻干燥以测定AAS。 DOM被从两个废水排放物中分离出来，一个是饮用水 以及两种实验室培养的藻类和细菌。DOM是根据 Leenher等人（2007年），该研究用有机氮富集了选定的部分。分离物 通过以下方法对其进行了表征:傅里叶变换红外光谱（FTIR）；固态核能 核磁共振；元素分析。分离的DOM组分冷冻保存 干燥并储存在干燥器中。在这项研究中，富含氮的胶体有机物 讨论了分数。包括8个参考文献、表格和图表。

Amino acids and amino sugars (AAAS) are important for drinking water treatment, because they can serve as substrate for biological activity, can serve as indicators for soluble microbial products, and may be precursors for the formation of nitrogenous disinfection byproducts. Despite these important needs, very little work is available to understand the nature of amino acids in drinking waters. The goal of this project was to measure amino acids in dissolved organic matter (DOM) isolates and bulk waters from drinking water sources. The samples, both bulk water and DOM, were collected from waters affected by seasonal algal blooms or wastewater discharges. Bulk water samples were collected from 10 full scale water treatment plants (WTPs) across the country during the summer/fall of 2006. The samples were analyzed for a multitude of water quality including: dissolved organic carbon (DOC), ultraviolet absorbance (UVA), total dissolved nitrogen (TDN), dissolved inorganic nitrogen (DIN), and dissolved organic nitrogen (DON). A 500 milliliter (mL) aliquot was concentrated and freeze dried for determination of AAAS. DOM was fractionated and isolated from two wastewater discharges, a drinking water reservoir, and two laboratory cultures of algae and bacteria. DOM was fractionated according to Leenheer et. al (2007), which enriched selected fractions with organic nitrogen. The isolates were characterized by the following methods: Fourier transform infrared spectroscopy (FTIR); solid-state nuclear magnetic resonance (NMR); and, elemental analysis. The isolated DOM fractions were freeze dried and stored in a desiccator. For this study, the nitrogen rich colloidal organic matter fraction is discussed. Includes 8 references, tables, figure.
