“…Other researchers confirmed that the peaks at 427 to 619 cm −1 observed in the FTIR spectrum are due to Mg-O vibration [18]. The peak at 3515 cm −1 , indicates the O−H group's stretching vibration [19]. The peak at 1474.46 cm −1 and 1354.84 cm −1 indicating the C−H bending of alkanes [19].…”

The green synthesis method is used to create magnesium oxide (MgO) nanoparticles in this study. SEM measurements and X-ray diffraction techniques are used to determine their crystal structure, as well as, FTIR to analyze the MgO na articles. Green synthesis of MgO nanoparticles are a good adsorbent for Eosin dye in aqueous solutions. Contact time, adsorbent mass, temperature, and Eosin dye concentration were all investigated. Freundlich isotherm models and the Eosin dye isotherm adsorption were well identical. The thermodynamic research yielded 101.4152 J/mol K, 0.02826397 kJ/mol, and −30.7005537 kJ/mol for the ΔS, ΔHand ΔGparameters, respectively. moreover, with R2=0.9228, the kinetic investigation revealed that the adsorption was pseudo-second-order.
