Study of Removal of Lead from Polluted Water with Using Different Adsorbents

In this study raw canola stalk (RCS), water vapor-activated biochar (BC), and magnetic iron oxide nanoparticles (Fe3O4) adsorbents were utilized to remove lead (Pb) from polluted solutions. The lead adsorption isotherm experiments were carried out using these adsorbents. The results indicated that the Fe3O4 nanoparticles is the best adsorbent for the lead pollutants’ removal. The results showed that the amounts of qm, Kl , R2 and SEE were 136.20 mg/g, 0.01919 L/mg, 0.9911, and 4.616, respectively. The entire results were compared in a 5% significance level.
