英文摘要: Some organic and mineral photocatalytic paints produced by Pigment company (Poland) were tested for the decomposition of benzo[a]pyrene (BaP) under UV-Vis. It appeared that latex (LX) and acrylic (IN) paints were more photoactive than mineral (FA and DR) ones. It was concluded that large amount of calcium carbonate and the presence of potassium sulfate in the mineral paints were detrimental for their photocatalytic activity. Potassium sulfate present in the paint formula resulted in the limiting access to the active anatase phase of TiO2 . However potassium sulfate is soluble in water, therefore it was removed from the paint surface by simply washing with distilled water and then enhanced activity of the photocatalytic mineral paints was observed. © 2015 Elsevier Ltd.
