Flow-through reactor for testing photocatalytic activity of multifunctional filter cloths

Popis výsledku v původním jazyce

Methods of measuring photocatalytic effectivity of immobilized nanolayers deposited e.g. on multifunctional filter clothes and membranes, described in literature, mostly suffer from mass transfer problems within the rather complex system: catalyst surface ? bulk contaminant ? light distribution. To avoid this drawbacks a new unit has been developed. Several strips of filter cloth are deposited side by side on inclined flat and smooth PTFE tile and covered by 4 mm thick PMMA-glass with UVA (290-380 nm) transparency > 90%. Each strip is individually flooded by solution of organic contaminant, which under UV illumination slopes down solely through the textile material, due to capillary forces and hydrophobicity of PTFE, and is finally collected in a beaker and transported again back to the input vial. The photocatalytic activity is determined via measurement of pollutant concentration descending by UV-VIS spectrophotometer. Results obtained and advantages and drawbacks of the method are d
