Equipment supporting the study of inorganic and organic sulphur-based compounds on the quality of water

这笔赠款中的设备将用于支持我的研究，该研究涉及在各种供水系统中发现的低氧化态无机和有机硫化合物的化学。这项研究的最终目的是为解决与水中硫化物有关的气味问题提供解决方案。要研究的大多数硫化物无法在商业上获得，需要为拟议的研究进行合成。几乎所有的低氧化态无机硫化合物在空气和其他氧化环境中都非常不稳定。因此，对这些化合物的分析应使用能够在分析过程中提供惰性环境的仪器。电化学分析仪(EA)，我正在申请资金的仪器之一，就有这种能力。它提供了从化合物的还原和氧化过程中产生的定性和定量信息。EA提供了几种电化学技术，如循环伏安法(CV)、线性和脉冲极谱以及计时电位法。从这些电化学技术收集的信息将使我能够利用硫元素的多种氧化态的独特性来表征合成的有机和无机硫化合物，这些氧化态的范围从-2到+6。此外，使用该设备可以很容易地完成在各种水系统中发现的还原硫化合物的形态形成。EA的一个非常独特的特点是，它能够在分析容易在空气中降解的化合物时提供惰性气氛。我还想申请一个有氧室的资金。这个密封室将允许我在一个不含空气的环境中进行一些实验。这将最大限度地减少硫化物降解的机会，而这是他们容易发生的。通过容纳常见的硫磺气味，该燃烧室将提供一个安全的工作环境。使用这些所要求的设备获得的最终结果将在加拿大和其他地方的饮用水质量改善方面找到有价值的应用。

The equipment in this grant will be used to support my study involving the chemistry of low oxidation-state inorganic and organic sulphur compounds that are found in various water distribution systems. The study is ultimately intended to provide solutions to the odour problems associated with sulphur compounds in water. Most of the sulphur compounds to be studied are not available commercially and will need to be synthesized for the proposed study. Nearly all of the low oxidation-state inorganic sulphur compounds are very unstable in the presence of air and other oxidizing environments. Therefore, the analysis of these compounds ought to be carried out using an instrument capable of providing an inert environment during the analysis. An Electrochemical Analyzer (EA), one of the instruments that I am requesting funding for, has this capability. It provides qualitative and quantitative information that arises from the reduction and oxidation processes of a compound. An EA provides several electrochemical techniques such as cyclic voltammetry (CV), linear and pulse polarography, and chronopotentiometry. The information gathered from these electrochemical techniques will enable me to characterize the synthesized organic and inorganic sulphur compounds by utilizing the uniqueness of the many oxidation states of the sulphur element which range from -2 to +6. Also, speciation of reduced sulphur compounds found in various water systems will easily be accomplished using this equipment. A very unique feature of an EA is its ability to provide an inert atmosphere during the analysis of compounds that are prone to aerial degradation. I would also like to request funding for an Aerobic Chamber. The chamber will allow me to conduct some experiments in an air excluded environment. This will minimize the chances of sulphur compounds degrading, which they are prone to. The chamber will allow for a safe working environment by containing the commonly encountered sulphur odours. The ultimate results obtained using these requested pieces of equipment will find valuable application in the improvement of drinking water quality here in Canada and elsewhere.
