0448117DionysiouAdvanced Oxidation Technologies (AOTs) are among the most promising emerging chemical oxidation processes for the treatment of organic pollutants of different chemical composition. AOTs are based on the generation of very reactive radicals, which in general have very high second order reaction rate constants with most organic contaminants. For this reason, AOTs are characterized with high reaction rates and short treatment times. In modern environmental engineering, AOTs are anticipated to play a crucial role in water treatment as stand-alone processes or in combination with conventional technologies. The PI proposes to expand on-going research and educational activities on the treatment of organic contaminants in water using AOTs. The proposed research will be useful for the development of new remediation technologies for the destruction of environmental contaminants and chemicals that can be used in chemical and biological terrorists actions. The educational plan will promote understanding of issues relevant to AOTs and drinking water quality and treatment, and will intensify interaction between drinking water professionals across disciplines.

高级氧化技术(AOTS)是处理不同化学成分的有机污染物的最有前途的新兴化学氧化技术之一。AOTS是基于非常活泼的自由基的生成，这些自由基通常与大多数有机污染物具有非常高的二级反应速率常数。因此，AOTS具有反应速度快、治疗时间短的特点。在现代环境工程中，AOT作为独立的工艺或与传统技术相结合，有望在水处理中发挥关键作用。国际倡议建议扩大正在进行的使用AOT处理水中有机污染物的研究和教育活动。拟议的研究将有助于开发新的补救技术，以销毁可用于化学和生物恐怖活动的环境污染物和化学品。该教育计划将促进对与AOTS以及饮用水质量和处理相关问题的了解，并将加强各学科饮用水专业人员之间的互动。
