Total organic carbon analyzer for environment study

由于人口增长和气候变化的影响，对水资源的需求日益增加，对改进水处理技术的需求变得极其迫切。目前，全世界有25亿人没有足够的卫生用水和废物处理用水，8.84亿人缺乏安全饮用水。这些惊人的数字加上越来越需要节约能源，为迫切发展高效和环境友好的水净化技术奠定了基础。安大略省西北部的经济在很大程度上依赖于采矿和纸浆造纸工业。随着环境法规的日益严格，采矿业和纸浆造纸行业需要改进的废水修复技术。总有机碳（TOC）分析仪被认为是研究废水修复和水净化的必备工具。我们建议购买一个高灵敏度的TOC分析仪，覆盖从4 ppb到25,000 ppm的TOC范围。所要求的总有机碳分析仪是迫切需要的，以支持申请人的NSERC发现研究计划，旨在开发新的绿色技术，用于采矿和纸浆和造纸工业的工业废物流的修复以及地下水的净化。提议的TOC分析仪代表了湖首和该地区研究能力的独特补充。由于大多数待分析的样品都是有毒的，因此将它们送去进行TOC分析是极其困难的。因此，所要求的TOC分析仪对于申请人开发基于纳米结构电催化剂和光催化剂的高效电化学氧化和光化学降解废水处理至关重要。TOC分析仪对于学生在水和废水分析方面的培训以及与其他科学家和行业的进一步合作也至关重要。申请人、博士后、研究生、本科生和科研人员每月使用TOC分析仪超过150小时。

The need for improved water treatment technologies has become extremely pressing as the effects of population growth and climate change place increasing demands on our water resources. Currently there is inadequate access to water for sanitation and waste disposal for 2.5 billion people worldwide and lack of safe drinking water for 884 million people. These staggering numbers coupled with the increasing need for energy conservation set the stage for the urgent development of efficient and environmentally friendly water purification technologies. The economy of Northwestern Ontario relies heavily on the mining and pulp & paper industries. Improved wastewater remediation technologies are needed by the mining and pulp & paper industries as environmental regulations are becoming stricter. A total organic carbon (TOC) analyzer is considered as a must-have tool for the studies of wastewater remediation and water purification. We propose to purchase a TOC analyzer with high sensitivity and covering a wide range of TOC from 4 ppb to 25,000 ppm. The requested total organic carbon analyzer is urgently needed to support the applicant's NSERC Discovery research program aiming at the development of new Green Technologies for the remediation of industrial waste streams in the mining and pulp & paper industries and the purification of groundwater. The proposed TOC analyzer represents a unique addition to the research capability at Lakehead and in this region. Because most of samples to be analyzed are toxic, it would be extremely difficult to send them away for TOC analysis. The requested TOC analyzer is thus essential for the applicant to develop efficient electrochemical oxidation and photochemical degradation for wastewater treatment based upon nanostructured electrocatalysts and photocatalysts. The TOC analyzer is also essential to student training in water and wastewater analysis, and to further collaborations with other scientists and industry. The requested TOC analyzer will be used over 150 hours per month by the applicant, postdoctoral fellows, graduate and undergraduate students, and research scientists.
