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.

对水中的氯氧化合物进行准确和可靠的分析对于有效部署氯基水处理至关重要。目前的标准方法不足以区分分子物种，如二氧化氯（ClO 2）从离子化合物，如二氧化氯（ClO 2-）和氯酸盐（ClO 3-）。开发一种简单的方法，具有合理的误差，现场使用的准确性和实验室设置的可靠性，有可能大大提高质量控制。拟议的Engage Plus项目将建立在先前资助的Manitoba大学无机化学家和Osorno企业公司水净化专家之间的Engage合作基础上，一家位于温尼伯的生物环境公司，是水质和消毒领域的行业领导者，专门为小型社区、医院和工业提供量身定制的解决方案。拟议的项目将扩展Engage合作的结果，以标准化一种使用市售的易于稀释的试剂测定水中痕量金属的新方法。一个成功的项目结果将有利于Osorno通过制定一个标准的方法，在氯氧生产质量控制。
