Preparation of new h-MoO3 rod-like microcrystals for effective removal of cationic dye in aqueous solution
h -MoO 3 rod-like microcrystals were successfully prepared using the hydrothermal microwave method and evaluated as an adsorbent for MB dye’s adsorption from an aqueous medium. The metastable phase with hexagonal structure ( h -MoO 3 ) was well confirmed by X-ray diffraction (XRD) and Raman spectros...

rod-like microcrystals were successfully prepared using the hydrothermal microwave method and evaluated as an adsorbent for MB dye’s adsorption from an aqueous medium. The metastable phase with hexagonal structure (
h
-MoO

) was well confirmed by X-ray diffraction (XRD) and Raman spectroscopy. FE-SEM images of these microcrystals confirm the rod-like morphology for all microcrystals synthesized. The better adjustment of the experimental data in the adsorption kinetics study was adjusted using the pseudo-first-order model, being

In general, for different temperatures (298 K, 308 K, and 318 K), the experimental data were better adjusted with the Temkin isotherm model, being the process of adsorption was favorable and spontaneous.
