Process of manufacture, application, recovery, reuse and final destination of bidimensional porous materia
NOVELTY – Two-dimensional porous materials production, application, regeneration and reutilization involve producing two-dimensional nanostructured porous materials, preferably nano-hydrotalcite, particularly nano-hydrotalcite. USE – Process for production, application, regeneration and reutilization of two-dimensional porous materials, preferably layered double hydroxides (LDH) or hydrotalcite-like compounds (HT) for use as sorbents in removal of environmental contaminants such as industrial effluents, raw water and treated groundwater. ADVANTAGE – The two-dimensional porous materials production, application, regeneration and reutilization method provides eco-friendly and non-toxic two-dimensional porous materials having above 99% discoloration efficiency and high efficiency for industrial wastewater treatment. DETAILED DESCRIPTION – Two-dimensional porous materials production, application, regeneration and reutilization involve producing two-dimensional nanostructured porous materials, particularly nano-hydrotalcite of general formula (I or II). M2+1-xM3+x(OH)2(A1-)x divide by nx tH2O (I) M2+zM3+y(OH)2z+3y-nk(A1-)kx tH2O (II). DESCRIPTION OF DRAWING(S) – The drawing shows a transmission electron micrograph of the hydrotalcite carbonate.
Main Application Field
D15 (Chemical or biological treatment of water, industrial waste and sewage – including purification, sterilising or testing water, scale prevention, treatment of sewage sludge, regeneration of active carbon which has been used for water treatment and impregnating water with gas e.g. CO2, but excluding plant and anti-pollution devices (C02).); E37 (Mixtures of many components; inorganic reactions and processes of general applicability.)
