Detoxification of Pb (II) from aquatic media via CaMgO2@g-C3N4 nanocomposite

In this article, CaMgO2@g-C3N4 nanomaterial with a surface area of 72.9 m2g−1 was fabricated by an ultrasonic process assisted with methanol solvent to eliminate Pb (II) from the aquatic system. The prepared sorbent was characterized using multiple techniques, including XRD, BET, XPS, TEM, and FTIR. The intra-particle diffusion, pseudo-second-order kinetics, and Langmuir adsorption model correspond to adsorption. The highest adsorption efficiency of CaMgO2@g-C3N4 was 2685 mgg−1 with optimum pH 3. Thus, CaMgO2@g-C3N4 exhibits superior adsorption, making it an effective adsorbent for cleanup Pb (II) from wastewater.
