AB  - Graphite-oxide (GO) is a valuable compound produced by the chemical oxidation of 
      graphite. The procedure for converting graphite into GO includes two steps: 
      oxidation and subsequent rinsing. Proper rinsing is essential to obtain 
      processable and applicable graphite-oxide. Traditionally, the rinsing involves 
      filtration or centrifugation; both processes are extremely time-consuming, 
      expensive, unsafe, and produce environmentally hazardous liquid waste in large 
      volume. This study reveals an alternative method to rinse graphite-oxide using a 
      Soxhlet extractor. Since only the vapor of the solvent is used for washing, 
      Soxhlet rinsing offers reuse of the same solvent for many automatic subsequent 
      cycles, leading to considerable solvent savings, reducing pollutants and work 
      time, and ensuring safer production. The quality of the produced GO is evaluated 
      by Raman spectroscopy, X-Ray diffraction (XRD), inductively coupled plasma (ICP), 
      elemental analysis, and electron microscopy. Moreover, we test the 
      electrochemical performances of reduced GO (rGO), the main final product of 
      graphite-oxide. Finally, we discuss the benefits involved in the suggested 
      rinsing method and compare its profitability with traditional methods. Soxhlet 
      rinsing is favored environmentally and economically. Particularly, the automatic 
      operation of many washing sequences saves labor time, and the reuse of the 
      washing solvent spares a large volume of chemically deleterious solvents.
