Application

  • Thermal Decomposition and Carbothermal Reduction: Examines the recycling and purification processes of Antimony(III) oxide from metal oxides, valuable for those interested in sustainable metallurgy (Karlsson et al., 2018).
  • Oxidation of Antimony(III) in Soil by Manganese(IV) Oxide: Studies the interaction between manganese oxide and antimony(III) oxide in soils, providing insights into environmental chemistry and soil remediation (Fu et al., 2018).
  • Adsorption of Antimony(V) onto Mn(II)-Enriched Surfaces: Focuses on how manganese oxide interacts with antimony(V), relevant for those studying adsorption processes and water treatment technologies (Liu et al., 2015).
  • Kinetic Modeling of Antimony(III) Oxidation and Sorption in Soils: Provides a kinetic model of antimony(III) interactions with environmental matrices, useful for environmental scientists and chemists involved in pollution control (Cai et al., 2016).
