Abstract

Some mechanism of photo-degradation of organic substances in aqueous solution by 185 nm UV is investigated.Firstly,185 nm UV photo-dissociates the ultra pure water.And,the H2O2 formed can be tested through experiments.It is proved that when 185 nm UV acts on the water,HO2and other active intermediates can be produced.Application 185 nm UV to the preparation system of ultra pure water can abate the TOC in ultra pure water to 0.3 μg/L,which meets the requirement ofUltra Large Scale Integrated Circuits(ULSIC).Meanwhile,185 nm UV has good effect on degrading TOC of organic substances in wastewater.It is a new method to degrade non-biodegradable,noxious and deleterious organic substances in aqueous solutions.It is good for expand the research on advanced oxidation processes (AOP) theoretically and environmental protection.
