Evaluation of the Properties of LaNiO3 Material Prepared by the Modified Proteic Method for Adsorption of Environmental Contaminants

LaNiO3 material was synthesized by modified proteic method, calcined at 900 °C/2 h in air atmosphere and was applied to remove environmental contaminants. LaNiO3 phase with a perovskite structure was formed in the calcined material, which has a surface area of 22 m2 g-1 and is formed by fine particles agglomerated, with pH of the zero charge point of 7.44. The removal of a model pollutant (Turquoise Blue dye) indicated that the better removal occurs in acidic pH and with adsorbent’s mass of 50 mg, showing average value around 90% of removal efficiency and 131 mg g-1 for adsorption capacity ...
