Abstract

Vanadium pentoxide and Tin dioxide nanoparticles were prepared by hydrothermal methods to remove methylene blue (MB) and bromothymol blue (BTB) dyes). First the prepared nanoparticles were heated at different temperature (90 ^oC and 500 ^oC). Then these nanoparticles were characterized by different methods such as UV/Visible, FT-IR Spectroscopy, X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), and Scanning Electron Microscopy (SEM). Our results explain that vanadium pentoxide nanoparticles appeared high remove activity against both types of organic dyes (MB and BTB) compared to tin dioxide nanoparticles. Furthermore,vanadium pentoxide heating at 90 ^oC has grain size (86.02 nm) more than that of Tin dioxide (48.02 nm) at same temperature. The activity of vanadium pentoxide is more than that of tin dioxide.may be related to high ionic potential (0.073), compared with Tin dioxide (0.048).
