This study aims to determine the effect of audiosonic sonication in normal modes on the formation of graphene oxide (GO) fromcarbon rods of zinc-carbon (ZnC) battery wastes. The method used in this study was sonication with an audiosonic frequency in normal modes, assisted by a surfactant solution derived from a commercial detergent. A graphite-detergent solutionwas exposed to audiosonicwaves using a frequency of 170 Hz for 3 hwith a patt on the surface of the solution. The graphite solution was a mixture of 0.8 g of graphite powder and 100 ml of distilled water that was mixed using a blender for 2 min. 25 ml of the solution was then taken and dripped with two drops of detergent solution containing 0.2 g detergent powder dissolved into 100 ml distilled water, so that a graphite-detergent solutionwas obtained. The tools used in this study included UV–Visible spectroscopy (UV–Vis), Fourier TransformInfraRed spectroscopy (FTIR), and a Scanning Electron Microscope (SEM). The solution that was audiosonicated showed a strong visible nodal patt on its surface. The UV–Vis spectroscopy produced absorbance peaks at wavelengths of 225 nmand 270 nm, and the FTIR indicated the presence of OH and C_C functional groups, which suggested the existence of GO. The SEMimages showed GO in the formof coral-like materials.
