We present a novel method of the solution plasma exfoliated techniques for the production of graphene sheets from recycled battery core at room temperature. This is a fast, simple and efficient method to produce graphene sheets using electrode pairs with DC high voltage power sources which were immersed in a solution. The as-prepared samples were characterized by various techniques such as scanning electron microscopy (SEM), atomic force microscopy (AFM), Raman scattering, and optical emission spectroscopy (OES). The obtained results showed that graphene has an average diameter of 1.5 m and a thickness of about 3 nm in respect of 7 to 10 layers. The prepared graphene was used as an effective adsorbent for the removal of methylene blue (MB) and Rhodamine B (RhB) from aqueous solutions. As a result, the adsorption efficiency of MB and RhB was determined to be 91% and 87 %, respectively. This is an attractive method to replace the previously reported graphene synthesis method.
