The photocatalysts TaOxNy were prepared by gas-solid reaction method with Ta2O5 as starting substance nitrified by NH3 under high temperature.The prepared samples were characterized by XRD,XPS,and UV-VIS.The results o...
The contents of acetic acid,chloroacetic acid and dichloroacetic acid as well as chloride ion in the chemicals were rapidly determined by ion chromatography.The analytical conditions were also optimized ,consequently,...
