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Bruce Locke和来自布拉格捷克等离子体物理研究所的Pavel Sunka以及克罗地亚萨格勒布大学的Natalija Koprivanac一起担任首席研究员。他们的总体目标是开发和分析一种用于降解水溶液中复杂工业和商业有机染料的高级氧化技术。具体来说，他们的工作是开发和评估用于偶氮染料、活性染料和3-苯基甲基型染料化学降解的液相放电反应器。该国际项目建立在每个实验室的优势之上，包括Locke在化学反应器（包括放电反应器）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。研究结果有望促进对以下方面的理解和最终发展：1)布拉格使用等离子喷涂技术的液相放电过程的新电极材料；2)塔拉哈西和萨格勒布结合气液相放电的新反应器配置；3)使用臭氧和/或过氧化氢与各种沸石结合降解染料的化学反应途径。如果成功，综合结果将产生更有效和有效的工艺，用于降解和去除商业、工业和制造业废水中的复杂有机染料。这个工程过程的项目通过使美国和中欧的专家能够结合互补的人才和共享共同感兴趣和能力的领域的研究资源，实现了推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.
