  • Patent number: 11884564
    Abstract: Claimed herein is a method of applying amorphous Co—SiOx to activate PMS and produce SO4·? due to the formation of Co(II)-Ov, pairs via the substitution of Si by Co. The inherent Co significantly change the electronic structure of O and Si atoms in the Co—SiOx via final state effects and increase the conductivity in terms of more effective electron transfers. The claimed method using Co—SiOx functions as a more effective oxidative catalyst for the faster degradation of pollutants. The simplicity of the synthetic procedures indicates that the conductive Co—SiOx could be used for the activation of PMS and other electrochemical applications on a wider scale.

  • Patent number: 11554360
    Abstract: The present invention covers a novel method for creating an adsorbent and the resulting novel adsorbent. The method may be used to remove pollutants/unwanted chemicals from water, air, other gases, biological fluids (such as blood, urine, lipids, protein fluids), and other fluids (such as fuel). The adsorbent may be used to remove heavy metals (for example, lead), organic pollutants, inorganic non-meal pollutants (for example, nitrates and bromates). Accordingly, the current invention has many applications including but not limited to water treatment, wastewater treatment, biomedical fluid treatments, gas cleanup, and fuel (oil, gas) cleanup.

  • Publication number: 20210113988
    Abstract: This invention describes a novel method for adsorbing heavy metals and a novel adsorbent for same. In one embodiment, the method is used to specifically remove Pb(II). In one embodiment, the adsorbent comprises modified carbon disulfide (“CS2”). In one or more embodiments the CS2 is modified with a graphene derivative. In one or more embodiments the graphene derivative is graphene oxide (“GO”).

  • Publication number: 20190046953
    Abstract: Ordered mesoporous carbon was prepared using COK-19 silica template. Ordered mesoporous silica COK-19 was synthesized with cubic Fm3m structure. Sucrose as the carbon precursor was impregnated into the mesopores of silica and converted to carbon through carbonization process using sulfuric acid as a catalyst. Ordered mesoporous carbon was obtained after the removal of silica framework using hydrofluoric acid. Several characterization techniques such as nitrogen adsorption-desorption isotherms, transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and elemental analysis were employed to characterize the OMC. The pore size analysis and TEM images confirmed that OMC has replicated the mesostructure of the COK-19. Results obtained from adsorption kinetics and isotherms suggest that the Pseudo-Second-Order Model and Langmuir Isotherm well described the experimental data. The adsorption study showed that the synthesized OMC has an adsorption capacity of 40.

  • Publication number: 20170121226
    Abstract: A multi-functional open graded friction course and a method of treating highway water runoff using the multi-functional open graded friction course are described herein. Open graded friction course is treated with an additive or additives, such as, but not limited to, an adsorbent. After treatment with the additive, the additive remains in the void spaces in the open graded friction course, thus creating a multi-functional open graded friction course. When highway or roadway water runoff flows into the void spaces, pollutants, such as heavy metals, are adsorbed by the additives and the water then flows laterally out of the multi-functional open graded friction course.
