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.

准确而可靠地分析水中的氧氯化合物对于有效部署基于氯的水处理至关重要。目前的标准方法不足以区分分子种类，例如二氧化氯 (ClO2) 与离子化合物，例如亚氯酸盐 (ClO2-) 和氯酸盐 (ClO3-)。开发一种具有合理误差、现场使用准确性和实验室设置可靠性的简单方法有可能大大增强质量控制。拟议的Engage Plus项目将建立在先前资助的马尼托巴大学无机化学家与Osorno Enterprises, Inc.的水净化专家之间的合作基础上。Osorno Enterprises, Inc.是一家总部位于温尼伯的生物环境公司，也是水质和消毒领域的行业领导者，专门从事为小型社区、医院和工业量身定制的解决方案。拟议的项目将扩展 Engage 合作的成果，以标准化一种使用市售、易于处理的试剂测定水中亚氯酸盐的新方法。项目的成功成果将通过开发氧氯生产质量控制的标准方法而使奥索尔诺受益。
