  • LAMINAR ZINC HYDROXIDE ORGANIC-INORGANIC NANOCOMPOSITES FOR USE IN THE REMOVAL AND DEGRADATION OF DYES FROM TEXTILE EFFLUENTS OR ORGANIC SUBSTANCES
    Publication number: 20210245143
    Abstract: The present invention relates to a method for removing dyes from textile effluents and other organic substances using nanocomposites based on zinc hydroxides and carboxylic acids capable of adsorbing and degrading. More specifically, the present invention consists of a method to generate new zinc hydroxide-based materials, which allows removal and degradation of methylene blue and other organic compounds from wastewater from industrial effluents, particularly those from textile industry.

  • METHOD FOR PRODUCING COPPER NANOPARTICLES AND USE OF SAID PARTICLES
    Publication number: 20180297121
    Abstract: The invention relates to copper nanoparticles and to a method for producing them, including the following steps: dissolving at least one copper salt, oxide or hydroxide in distilled water in a container; dissolving at least one stabilizer in distilled water in a container; mixing the two solutions in a reactor; adding a primary complexing agent; adding an alkali; adding an anti-foaming agent; adding at least one reducing agent, stopping the reaction by cooling to a temperature reaction between 0° C. and 25° C. while maintaining the stirring; adding at least one antioxidant; adding at least one secondary complexing agent; and maturing and washing the mixture; The invention also relates to the use of copper nanoparticles.
