Quantification of Total Organic Halogen in Water Treatment

人口增长、气候模式变化和经济活动需求的增加日益影响着包括河流、湖泊和地下水在内的自然水的质量和数量。卡尔加里大学和ACWA（推进加拿大废水资产），一个全球独特的全规模实验废水和饮用水回用研究设施，在水处理技术方面处于领先地位，以(1)去除废水中的顽固污染物；(2)尽量减少饮用水中不受管制的有毒副产物的形成；(3)通过污水回收增加水资源；(4)评价对接收水域、生物群和人类的生态和健康影响。为此目的，至关重要的是评估天然和处理过的水作为一个整体混合物的质量，包括已知和未知的化合物。总有机卤素（TOX）是水研究的关键测量方法，它捕获了所有有机卤化物质，包括持久性有机污染物和消毒副产物。此外，TOX按卤素类型进行量化，即总有机氯（TOCl）、总有机溴（TOBr）和总有机碘（TOI）。TOCl， TOBr和TOI是非常有价值的水质参数，因为溴化和碘化有机化合物比氯化有机化合物毒性大得多。这些关键的综合测量可以评估水质，这将推进研究并推动新的水处理技术和生态监测工作的设计。这项RTI拨款提案要求获得TOX仪器的资金，该仪器将支持化学、工程和生物科学系的几个研究小组进行与水有关的研究。所要求的TOX仪器将是卡尔加里大学和阿尔伯塔省可用于研究的第一个此类仪器。

Population growth, changing climate patterns, and increasing demands by economic activities are increasingly affecting the quality and quantity of natural waters including rivers, lakes and groundwater. The University of Calgary and ACWA (Advancing Canadian Wastewater Assets), a globally unique full-scale experimental wastewater and potable reuse research facility, are leading on water treatment technologies to (1) remove recalcitrant contaminants from wastewater; (2) minimize the formation of unregulated toxic byproducts in drinking water; (3) augment water resources through wastewater reclamation; and (4) evaluate ecological and health effects to receiving waters and in biota and humans. To this end, it is crucial to assess the quality of natural and treated waters as a whole mixture, including known and unknown compounds. Total organic halogen (TOX) is a critical measurement for water research that captures all the organic halogenated material including persistent organic pollutants and disinfection by-products. Furthermore, TOX is quantified by halogen type, that is, total organic chlorine (TOCl), total organic bromine (TOBr), and total organic iodine (TOI). TOCl, TOBr, and TOI are extremely valuable water quality parameters because brominated and iodinated organic compounds are much more toxic than chlorinated organic compounds. These key comprehensive measurements can assess water quality that will advance research and drive the design of new water treatment technologies and ecological monitoring efforts. This RTI grant proposal requests the funds to obtain the TOX instrument that will support water-related research of several research groups from the Departments of Chemistry, Engineering and Biological Sciences. The requested TOX instrument will be the first of its kind available for research at the University of Calgary and in the province of Alberta.
