Abstract
A silica membrane filterincludes a porous substrateand a silica membraneformed on the porous substrate, the silica membranehaving an aryl group. The silica membranehas an atomic ratio Si/C, as determined by elemental analysis using energy-dispersive X-ray spectrometry (EDX), in the range of 0.2 to 15. The silica membranepreferably has a thickness in the range of 30 nm to 300 nm and an X/Y, a ratio of an absorption intensity X of a Si—O—Si bond to an absorption intensity Y based on the aryl group in a Fourier transform infrared absorption spectrum (FT-IR), in the range of 5.0 to 200.
