Enhancing mechanism of arsenic(iii) adsorption by MnO₂-loaded calcined MgFe layered double hydroxide.

ABSTRACT: The use of MnO₂/MgFe-layered double hydroxide (MnO₂/MgFe-LDH) and MnO₂/MgFe-layered double oxide (MnO₂/MgFe-LDO_{400 °C}) for arsenic immobilization from the aqueous medium is the subject of this research. Fourier transform infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, and transmission electron microscopy were used to characterise MnO₂/MgFe-LDH and MnO₂/MgFe-LDO_{400 °C}. Based on our developed method, MnO₂ was spread on the clay composites' surfaces in the form of a chemical bond. The clay composite exhibited a good adsorption effect on arsenic. The experimental findings fit the pseudo-second-order model well, indicating that the chemisor
