| description | This paper reports the development of a new method. Production of modified clay with magnetic properties based on natural clay from the Shymkent deposit (MnFe2O4/Shymkent nanocomposite), determination of its chemical composition and structure, as well as the study of basic physicochemical properties. The resulting magnetic nanocomposite was then used as an adsorbent to remove nickel (II) ions from wastewater. The prepared magnetic nano composite was then used as adsorbent to remove Ni (II) ions from wastewater, and the optimal conditions for determining thermodynamic and kinetic parameters were evaluated. It was determined that the natural сlay from the Shymkent deposit is a promising material for the modification of the materials. The advantage of such magnetic adsorbents in comparison with the natural materials used as adsorbents is their higher adsorption capacity and theability to control them using a magnetic field. To characterize the modified adsorbents, various assays were used, such as EMP andXRD analysis. The textural properties of the materials were determined by analyzing N2 adsorption-desorption isotherms at 77 K. It is shown that almost all textural and adsorption characteristics of MnFe2O4/Shymkent have significantly improved as a result of the modification made. It was concluded that the MnFe2O4/Shymkent adsorbent obtained in the work can be used for effective wastewater treatment to remove nickel ions. |
