Development of a standardized analytical protocol for determination of chlorite concentration using thiourea dioxide

准确和可靠地分析水中的氯氧化合物是有效部署氯基水处理的关键。目前的标准方法不足以区分二氧化氯(ClO2)等分子物种与亚氯酸盐(ClO2-)、氯酸盐(ClO3-)等离子化合物。在实验室环境中开发一种具有合理误差、现场使用的准确性和可靠性的简单方法，有可能极大地加强质量控制。拟议的Engage Plus项目将建立在马尼托巴大学无机化学家与Osorno Enterprise，Inc.之间以前资助的Engage合作的基础上，Osorno Enterprise，Inc.是一家总部位于温尼伯的生物环境公司，是水质和消毒领域的行业领先者，专门为小型社区、医院和工业提供量身定制的解决方案。拟议的项目将扩大Engage合作的成果，以标准化一种使用商业上可获得的、易于操作的试剂测定水中亚氯酸盐的新方法。一个成功的项目成果将使Osorno受益，因为它将开发一种用于氧氯气生产的质量控制的标准方法。

Acccurate and robust analysis of oxychlorine compounds in water is essential to the effective deployment ofchlorine-based water treatment. The current standard methods are inadequate for the discrimination ofmolecular species such as chlorine dioxide (ClO2) from ionic compounds such as chlorite (ClO2-) and chlorate(ClO3-). The development of a simple method with reasonable error, accuracy for field use, and reliability inlaboratory settings has the potential to greatly enhance quality control. The proposed Engage Plus project willbuild on the previously funded Engage collaboration between inorganic chemists at the University of Manitobaand the water-purification experts at Osorno Enterprises, Inc., a Winnipeg-based bio-environmental companyand industry leader in water quality and disinfection, specializing in tailored solutions for small communities,hospitals and industry. The proposed project will expand on results from the Engage collaboration tostandardize a new method for chlorite determination in water using commercially available, easy-to-handlereagents. A successful project outcome would benefit Osorno by developing a standard methodology forquality control in oxychlorine production.
