Studies on Liposome-encapsulated-chemical Actinometer in UV-disinfection by Low Pressure UV Lamp: Bio-chemical Actinometer in UV-Disinfection

A liposome-encapsulated lodide-lodate chemical actinometer has been synthesized to monitor the inactive microorganisms damaged by UV disinfection. Relationship between bio-dosimeter and liposome-encapsulated lodide-lodate chemical actinometer under low pressure UV lamp was investigated. Similar dose rates between chemical actinometer and bio-dosimeter were observed. The particle sizes of liposome-encapsulated lodide-lodate chemical actinometer ranged from 1 to 3 μm. The chemical actinometer after encapsulation by the liposome was concentrated to 7 times by a TOC assay. Results indicate that it is possible to apply the liposome-encapsulated lodide-lodate chemical actinometer in UV water disinfection systems.
