Soybean curd residue (SCR) as carbon sources is able for absorbance materials. The utilization of SCR has provided new opportunities and challenges for advanced materials research. The transformation of the carbon structure of the SCR provided graphene-like structures with high surface area and metal ion absorbing capability. The carbon-based adsorbent material was prepared by pyrolysis method. The transformation of carbon structure to produce graphene structure was carried out by Hummers method. Magnetization was carried out by the addition of FeCl3.6H2O and FeCl2.4H2O to form a magnetite compound (Fe3O4) and was applied as absorbance of metal ions. Separation process was carried using magnetic field. The samples were characterized by scanning electron microscopy (SEM), fourier-transform infrared (FTIR), Brauner Emmet Teller (BET) and atomic absorption spectrophotometry (AAS). The results showed that the carbon from the SCR had graphene like-structure which was able to absorb nickel metal ions.
