Description
Summary:This report investigates the elimination of hazardous Rhodamine B dye (RhB) from an aqueous medium utilizing MgTiO[sub.3] @g-C[sub.3] N[sub.4] nanohybrids manufactured using a facile method. The nanohybrid MgTiO[sub.3] @g-C[sub.3] N[sub.4] was generated using an ultrasonic approach in the alcoholic solvent. Various techniques, including HRTEM, EDX, XRD, BET, and FTIR, were employed to describe the fabricated MgTiO3@g-C3N4 nanohybrids. RhB elimination was investigated utilizing batch mode studies, and the maximum removal was attained at pH 7.0. The RhB adsorption process is more consistent with the Langmuir isotherm model. The highest adsorption capacity of MgTiO[sub.3] @g-C[sub.3] N[sub.4] nanohybrids for RhB was determined to be 232 mg/g. The dye adsorption followed a pseudo-second-order model, and the parameters calculated indicated that the kinetic adsorption process was spontaneous. Using ethanol and water, the reusability of the nanomaterial was investigated, and based on the results; it can be concluded that the MgTiO[sub.3] @g-C[sub.3] N[sub.4] nanohybrids are easily regenerated for dye removal. The removal mechanism for the removal of RhB dye into MgTiO[sub.3] @g-C[sub.3] N[sub.4] nanohybrids was also investigated.
