The Adsorption Efficiency of Lead From Post-Tin Mining Water using Nanomagnetic Fe3O4/Chitosan Portunus pelagicus shells
Adsorption was carried out on the water of post tin mining using nanomagnetic Fe3O4/chitosan from Portunus pelagicus shells. Nanomagnetic Fe3O4/Chitosan was prepared for lead adsorption. The nanomagnetic Fe3O4 was characterized through XRD and chitosan was characterized through FTIR The concentration of Pb in post tin mining water is 0,36 ppm. This study varied the mass of Fe3O4 and stirring time. The adsorption results were analyzed by AAS and obtained the largest adsorption efficiency (58,33%) at stirring 30 minutes with a mass of Fe3O4 of 75 mg.
