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.

对水中氧气化合物的能力和鲁棒分析对于有效的基于氯的水处理至关重要。当前的标准方法不足以歧视分子物种，例如氯酸盐（Clo2-）和氯酸盐（Clo3-）等离子化合物的二氧化氯（ClO2）。开发具有合理错误，现场使用准确性以及内置设置的简单方法的开发有可能极大地增强质量控制。拟议的参与者Plus Project Willbuild在Manitoba和Osorno Enterprises，Inc。的水上化学专家的无机化学家之间的先前资助的参与合作中，这是一位位于温尼伯的水质和消毒的生物 - 环境公司和消毒者领导者，专门针对小型小型社区的裁缝解决方案，专门针对小型社区的裁缝解决方案。拟议的项目将扩大参与协作的结果，以使用市售，易于处理的含水在水中确定的氯酸盐确定方法。成功的项目结果将通过在氧氯生产中开发标准的方法来控制质量控制，从而使Osorno受益。
