The Use of Larger Volumes in a Collimated Beam Setup

摘要

Research into the conversion of organic micropollutants revealed that with medium pressure (MP) UV-lamps, an increase in genotoxic activity in one of two tested bacterial strains in the Ames II test may be obtained. To study the factors that affect formation of genotoxic by-products, volumes ≥ 500 mL are required. It is possible to use a collimated beam (CB) setup with water layers up to 10 cm deep. Both photolysis as well as oxidation constants of model compounds tested in a water matrix containing NOM stayed constant, independent of the depth of the water layer applied.View full textDownload full textKeywordsUV Oxidation, Photolysis, Micropollutants, By-products, Collimated BeamRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01919512.2012.650612
