The Analysis of morphology, porosity and absorption of Fe3O4 nano particles coated with SiO2-NPs has been carried out; use polyethelen glycol as a core for forming core-shell Fe3O4@ SiO2/PEG. SiO2-NPs is prepared from quartz sand by hydrothermal and coprecipitation methods; Fe3O4-NPs have been prepared from iron sand with the co-precipitation method. Characterization of morphology with SEM-EDX; porosity (Ap, Vp, Dp) using BET (adsorption and disorption); and Pb (II) adsorption with AAS. Obtained the larger particle size, the lower porous for the less SiO2-NPs composition. The best formation of core-shell composition is Fe3O4@ SiO2 /PEG for Fe3O4 and SiO2 (composition 1:1; 1:3 and 3:1), the largest Pb (II) adsorption rate of 2.34 mg/g and absorbed concentration of Pb (II) 23.4 mg /l.
