In the present research, an effective adsorbent as titled multiwall carbon nanotube/ZnCo- Zeolite imidazole frameworks (MWC/ZIF) was prepared and used for removal of Pb(II) ion from effluent samples. After separating the adsorbent from the solution, the amount of Pb(II) ion in the solution was measured using an atomic absorption device. Based on this, various experimental parameters effective on lead removal including pH, ionic strength, time, temperature, and Pb(II) ion concentration were investigated. Various kinetic models were also studied to assess adsorption kinetics of Pb(II) ions onto surface of MWC/ZIF nanocomposite. With reference to the obtained findings, the produced nanocomposite was assumed as an effective adsorption approach for removal of Pb(II) ions from effluent samples.
