| Popis: | In this research, the practical feasibility of sawdust waste products from wood-processing industries was evaluated for the elimination of Pb+2 and Co+2 metal ions from mono and binary aquatic solutions. The batch method was used to achieve optimum conditions of including the amount of sorbent, pH, process time, and concentration of metal ions. The absorptive cycle reported maximum removal of lead and cobalt within pH range 6.0 at an initial concentration of 10 mg L–1. Kinetics data collected during the adsorption of both metals is better represented in a pseudo-second-order layout. The equilibrium of adsorption is based on the concept of Langmuir adsorption layout. Thermodynamic parameters demonstrated the feasibility, spontaneity, and endothermic character of heavy metal sorption. The sorption of metal ions was verified by instrumental experiments for example scanning electron microscope (SEM), energy dispersive x-ray spectrometry (EDX), and Fourier transform infrared spectroscopy (FTIR). Thus, sawdust can be an effective material for removing Pb+2 and Co+2 ions from aquatic solutions. |
