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).

Nanotechnology has proven its presence in many fields such as sensing pollutants and water pollution, Nanomaterials such as metallic, metal oxides, carbon compounds, nanocomposites and filtering membranes have been used for filtering membranes in wastewater treating [5].metal oxides such as(Al2O3, V2O5, Mn2O3, SnO2, La2O3 are used in water purification technology due to their ability to separate the chemical and biological properties of water [6]
Summary
Water is the essential element of life and it is a precious resource for human civilization. Clean water is a major global challenge in the twenty-first century. Dyes are considered one of the most critical organic pollutants that cause water pollution and cause many diseases. Nanomaterials are considered to be the absorbing materials for water pollutants by adsorption [2]. Nanotechnology has proven its presence in many fields such as sensing pollutants and water pollution, Nanomaterials such as metallic, metal oxides, carbon compounds, nanocomposites and filtering membranes have been used for filtering membranes in wastewater treating [5].metal oxides such as(Al2O3, V2O5, Mn2O3, SnO2, La2O3 are used in water purification technology due to their ability to separate the chemical and biological properties of water [6]. The dye absorption is done on the surface of nano absorbent materials. First the contaminants are absorbed on the surface of the nanoparticles, the solution is accompanied by a change in the pH, a change in temperature, etc.[7]
