The results showed that UV radiation mainly led to crystal destruction and molecular degradation on the surface and recrystallization on the interior part of the sample.
The degradation ration of Direct Fast Scarlet 4bs and Basic Green are up to about 90%, indicating that the sample on the photocatalytic degradation of dyes has a broad spectrum.
Sample's Raman spectroscopy on Model T64000 color scattering spectrometer with CCD is obtained and photocatalytic degradation of the sample top-methyl phenol are compared.
