10月29日，应中国科学院城市污染物转化重点实验室和付明来研究组邀请，Chemical Engineering Journal杂志主编、辛辛那提大学环境科学与工程学院Dionysiou教授来城市环境研究所进行学术交流访问。 

　　Dionysiou教授做了题为“Treatment of Cyanotoxins and Contaminants of Emerging Concern in Water Using Advanced Oxidation Processes”的学术报告，介绍了当前其研究重点，即紫外和太阳光先进氧化技术、TiO₂光催化等；详细介绍了藻毒素在新鲜水系统存在的问题、先进氧化技术和纳米技术在水处理中的应用和机理；并讨论了TiO₂光催化去除微囊藻素的反应动力学及反应路径、单分散TiO₂协同生物方法降解水中污染物、先进氧化技术/UV光下降解污染物的机理等问题。报告引起了与会科研人员的浓厚兴趣和热烈响应，大家就相关问题进行了深入探讨。 

　　付明来研究员与Dionysiou教授交换了分别印有城市所、辛辛那提大学标志的杯子。此次交流，推进了双方合作的持续深入开展。 

　　Dionysiou教授简介:
