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 contaminated 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 values 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 economically feasible technology to filter microorganisms biological zone to purify the water.
