2021/6/15 · The samples were mixed with acetonitrile at volume ratio of 1:1, filtered through 0.22 µm PTFE syringe filter and analyzed by high-performance liquid chromatography (HPLC). The improved visible light utilization of the catalysts was evaluated by apply a UV filter (UV420) to remove the UV portion of solar light, and compared the photocatalytic activity of the catalysts.

PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant. Moreover they can be used to filter aqueous solutions as well, but because of their hydrophobic characteristics, they must be pre-wetted with ethanol or methanol before the filtration of aqueous media
