Abstract

The current study introduces a one-pot technique for synthesizing an environmentally benign and cheap composite adsorbent, namely ZnO-PPAC, for the adsorption of Pb(II). The designated adsorbent was prepared by incorporating green synthesized zinc oxide (ZnO) nanoparticles on activated carbon-derived from pineapple peel. The prepared adsorbents were characterized using XRD, SEM, EDS, FTIR, and BET techniques. The XRD pattern verifies that the ZnO was successfully synthesized and immobilized onto the PPAC in a one pot synthesis system. The surface areas of ZnOPPAC and PPAC adsorbents were 13.62 m2/g and 961.96 m2/g, respectively. The FTIR evaluation of the ZnO-PPAC adsorbent revealed several characteristic absorption peaks corresponding to -OH groups, C-O groups, C=C groups, C-N groups, and M-O groups. It was revealed that the adsorption of Pb(II) on the ZnO/PPAC adsorbent would not require any pH adjustment. The adsorption kinetics demonstrated that the adsorption of Pb(II) ions on PPAC and ZnO-PPAC better fitted pseudo-second-order kinetics (R2 = 0.999, both for PPAC and ZnO/PPAC) and followed the Freundlich model (R2 = 0.989 and 0.987 for PPAC and ZnO/PPAC adsorbent). According to the Freundlich model, the adsorption of Pb(II) ions onto the designated adsorbents involves a multilayer process. The maximum adsorption capacities of ZnO/PPAC and PPAC were calculated as 769 mg/g and 667 mg/g, respectively. Thermodynamic analysis indicated an exothermic and spontaneous nature, as suggested by the negative values of ΔHº and ΔGº. In summary, both the prepared adsorbents greatly exhibited a high adsorption capacity of Pb(II) ions that can be used for environmental remediation.
