Environmental remediation by an integrated microwave/UV-illumination method II. Characteristics of a novel UV-VIS-microwave integrated irradiation device in photodegradation processes

摘要

In this brief article we examined the characteristics of novel UV-VIS-microwave integrated irradiation device and explosive its usefulness using the now well-established photo-degradation of a cationic dye (rhodamine-B; RhB) as a test substrate. The device consistent of a double quartz cylindrical plasma photoreactor (DQCPP) equipped with a microwave (MW) powered electrodeless Hg/Ne irradiation source. The latter is activated only by the MW radiation. The integrated MW-UV-VIS radiations so produced and incident on the DQCPP reactor significantly enhanced the decomposition of the RhB dye through simultaneous photocatalytic and photosensitization processes.
