Structural, Morphological and Methanol Sensing Properties of Jet Nebulizer Spray Pyrolysis Effect of TiO2 Doped SnO2 Thin Film for Removal of Heavy Metal Ions

Lead (Pb) and mercury (Hg) are two highly toxic heavy metals which must be removed completely or reduced to very low levels in drinking water supplies. TiO2:SnO2 nanoparticles and thin films were exploited for this purpose. TiO2:SnO2 nanoparticles were prepared by using the sol–gel combustion synthesis technique. The synthesized particles obtained were used in the analysis of the heavy metals of (Pb and Hg). The same material was used to deposit TiO2:SnO2 thin films by employing the Jet Nebulizer Technique (JNT). The films were subsequently characterized and used as adsorbents in the removal of heavy metal residues from con- taminated water samples. The developed TiO2:SnO2 absorbents were characterized by transmission electron microscopy. The crystallite size of the prepared samples varied from 27 nm to 33 nm. The shape of the response curve for a given temperature variation depends on the well agreement with previously reported val- ues ranging from zero for clean air to high positive values for strong interaction with reducing gas molecules. The application of these materials in many water filters may be helping to filter the sediments and economi- cally feasible technology to filter microorganisms biological zone to purify the water.
