An International Collaboration on Electrical Discharge Reactors for the Degradation of Organic Dyes

这个国际合作研究项目涉及三个研究小组，一个在美国，一个在捷克共和国，一个在克罗地亚。塔拉哈西佛罗里达州立大学的布鲁斯·洛克与布拉格捷克等离子体物理研究所的帕维尔·桑卡和克罗地亚萨格勒布大学的娜塔莉亚·科普里瓦纳克共同担任首席研究员。他们的总体目标是开发和分析一种高级氧化技术，用于降解水溶液中复杂的工业和商业有机染料。具体地说，他们的工作特点是开发和评估用于偶氮染料、活性染料和3-苯甲基类型染料化学降解的液态放电反应器。国际项目建立在每个实验室的优势基础上，包括洛克在包括放电反应器在内的化学反应分析方面的专业知识，Koprivanac在涉及有机染料合成和降解的化学反应方面的专业知识，以及Sunka在等离子体物理和气体和液体应用的放电反应器分析方面的优势。预计这些发现将有助于更好地理解和最终开发：1)布拉格使用等离子喷涂技术的液态放电过程的新电极材料，2)塔拉哈西结合气体和液体放电的新反应器配置，以及3)在萨格勒布使用臭氧和/或过氧化氢结合各种沸石降解染料的化学反应途径。如果成功，综合结果将产生更高效和更有效的工艺来降解和去除商业、工业和制造业废水中的复杂有机染料。这个工程工艺项目通过使美国和中欧的专家能够在相互感兴趣和能力很强的领域结合互补的人才和共享研究资源来实现促进科学知识的计划目标。

INT 0086351LockeThis international cooperative research project involves three research groups, one in the Unites States, one in the Czech Republic and one in Croatia. Bruce Locke of Florida State University, Tallahassee, serves as the principal investigator along with partners Pavel Sunka from the Czech Institute of Plasma Physics, Prague, and Natalija Koprivanac of the University of Zagreb, Croatia. Their overall objective is the development and analysis of a type of advanced oxidation technology for the degradation of complex industrial and commercial organic dyes in aqueous solutions. Specifically their work features development and evaluation of liquid phase electrical discharge reactors for the chemical degradation of azo dyes, reactive dyes, and 3-phynylmethand type dyes.The international project builds upon the strengths of each lab including Locke's expertise in analysis of chemical reactors including electrical discharge reactors, Koprivanac's expertise in chemical reactions involving synthesis and degradation of organic dyes, and Sunka's strengths in plasma physics and analysis of electrical discharge reactors for both gas and liquid applications. Findings are expected to lead to an improved understanding and eventual development of: 1) new electrode materials for liquid phase electrical discharge processes using plasma-spraying technology in Prague,2) new reactor configurations combining gas and liquid phase discharges in Tallahasee, and, in Zagreb, 3) chemical reaction pathways for dye degradation using ozone and or hydrogen peroxide in combination with various zeolites. If successful, combined results should yield more efficient and effective processes for the degradation and removal of complex organic dyes from commercial, industrial and manufacturing wastewater.This project in engineering processes fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence.
