Effect of Various Deep Eutectic Solvents on the Sustainable Synthesis of MgFe2O4 Nanoparticles for Simultaneous Electrochemical Determination of Nitrofurantoin and 4-Nitrophenol

“…It can be clearly perceived that the lattice parameter and the volume of the unit cell calculated for the cubic spinel phase of magnesium ferrite are consistent with the values given in predominant research papers. 27,30,37 Besides, the crystallite size of the as-attained MgFe 2 O 4 has considerably reduced in comparison to the recent report by Soldner et al 47 which proves the supremacy of the particular DESs over the explored solvents in virtue of their reduced reaction time and synthesis temperature.…”

“…The indexed peaks constitute a distinctive mono phase spinel configuration associated with space group Fd-3m, which matches well with JCPDS Card No. 71-1232 . A low-intense secondary phase of α-Fe 2 O 3 is exhibited in ferrites produced from choline chloride:oxalic acid and choline chloride:urea DESs, whose phase reflections are very weak compared to the spinel MgFe 2 O 4 phase .…”

“…71-1232. 27 A low-intense secondary phase of α-Fe 2 O 3 is exhibited in ferrites produced from choline chloride:oxalic acid and choline chloride:urea DESs, whose phase reflections are very weak compared to the spinel MgFe 2 O 4 phase. 39 High crystallinity and good resolution of the XRD patterns of MFM, MFEG, and MFF indicate the high reaction efficiency of the methodology at a temperature much lower than that of the stated solid-state reactions.…”
