FIELD OF THE INVENTION
This invention relates to Synthesis of CuO/r-GO for the decontamination of wastewater containing highly toxic inorganic contaminants.
BACKGROUND OF THE INVENTION
CN101405223B says that the present invention relates to methods and compositions for removal of arsenic and heavy metals from water.
Research Gap: Our method is based on plant derived material and sonochemical mixing
US9162902B2 says that a method for the removal of aqueous phase selenite and selenate species using TiO2 assisted photocatalysis employing the use of artificial light, or solar radiation, in conjunction with EDTA as a hole scavenger. Among the two processes, UV-lamp assisted photocatalysis has the highest efficiency comparatively followed by solar light assisted photocatalysis. TiO2 mediated photocatalysis in conjunction with EDTA as an h+ scavenging agent is an efficient technique for selenium ion removal.
Research Gap: Our work demonstrated the adsorptive removal of toxic contaminants
US 20210060522A1 says that Materials and methods for removing contaminants from liquids such as water are provided. The materials are graphene oxide-based materials that are chemically modified to comprise functional groups that adsorb a wide variety of pollutants such as heavy metals, nitrates, and phosphates.
Research Gap: We used the biogenic CuO nanoparticles for the incorporation into graphene and used this material in the removal of cadmium and hexavalent chromium ions.
SUMMARY OF THE INVENTION
This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention.
This summary is neither intended to identify key or essential inventive concepts of the invention and nor is it intended for determining the scope of the invention.
To further clarify advantages and features of the present invention, a more particular description of the invention will be rendered by reference to specific embodiments thereof, which is illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the invention and are therefore not to be considered limiting of its scope.
The exposure of inorganic and organic pollutants in water bodies has become one of the most serious issues in the world. Different conventional methods are available to be used to remove these contaminants from water and wastewater. The adsorption-based removal used to decontaminate the water containing harmful contaminants is efficient, low-cost, and eco-friendly. The nanocomposite-based materials have also received a lot of attention for their adsorptive removal of heavy metal contaminants. Cd2+ and Cr6+ ions are very hazardous to all living forms. These contaminants cause many life-threatening problems in humans. In this work, a sustainable synthetic approach has been utilized in the development of CuO/r-GO, and this synthesised nanocomposite will be used to remove Cd2+ and Cr6+ ions from wastewater.
