Synthesis of MGO Nanostructures Via Simple Sonochemical Method for Adsorption of Low Concentrations of Amoxicillin from Aqueous Phase
Abstract
MgO nanostructures were synthesized through a simple sonochemical approach to be applied for removing low
concentrations of amoxicillin from the liquid phase. As results, scanning electron microscopy (SEM) exhibited favorable
structure for as-synthesized MgO nanostructures with low aggregation. In the following, adsorption of amoxicillin by MgO
nanostructures was optimized via response surface methodology (RSM) based on central composite design (CCD).
Accordingly, the maximum amoxicillin removal of 79.32% was obtained at amoxicillin concentration of 4.62 mg/L, reaction
time of 73.78 min and MgO nanostructures dosage of 2.09 g/L. The results showed that increasing MgO nanostructures
dosage and elapsed time, together with decreasing the initial amoxicillin concentration, favored the removal of amoxicillin
through the adsorption process.
