Means for determination of photo-catalytic activity of surface, in which means is formed in form of test strips which is directly applicable on surface whose photo catalytic activity is to be determined

摘要

Means is formed in form of test strips which is directly applicable on surface whose photo-catalytic activity is to be determined. The test strip (1) has a substrate (2) for immobilization of photo-catalytic chemically degradable substance in particular liquid or solute form under effect of electromagnetic radiation. The substance is immobilized in such a manner on the substrate that it treads in contact with test strip after applying on surface. A barrier (3) is arranged on the substrate and is formed of such material that after applying test strips on the surface, the radiation of photo-catalytic chemically degradable substance is immobilized on the substrate under effect of electromagnetic radiation and is possible with electromagnetic radiation. An independent claim is also included for the method.
