Abstract : In order to remove lead from an aqueous solution taken from industrial effluent and soil contaminated by crude oil, the study used snail shell nanoparticles, a plentiful and inexpensive resource. The adsorbent was described. The adsorbent was subjected to Fourier transform infrared (FTIR) examination. The morphological properties of the adsorbent were examined using a scanning electron microscope (SEM). Experimental data was optimization using Mathematica software 11.0.2.1. Temperature, contact time, and concentration were examined. Thermodynamics, kinetics, and equilibrium adsorption isotherms were examined. Langmuir, Freundlich, and isotherm models were used to assess the experimental data. Pseudo-first order, pseudo-second order, and intra-particle models were fitted to the kinetics data. The adsorption isotherm developed fits the Freundlich isotherm model well, according to the results, with the maximum correlation coefficient (R2) of 0.966. According to the thermodynamic study, the lead removal process by the snail shell nanoparticles was feasible, exothermic, and spontaneous. These findings suggest that lead can be successfully removed from aqueous solutions using snail shell nanoparticles as an adsorbent.
