We present a study of adsorption of Cresyl Violet (CV) in aqueous solution on sonicated Graphite Oxide (sGO). For comparison, we also show adsorption results of Methylene Blue (MB) and Acridine Orange (AO) performed in the same conditions. The adsorbent was synthesized by the Tour's method followed by washing in water and ethanol and sonication, without any reduction, and studied by Raman, IR, UV-Vis, SEM and TEM techniques. Our results show that adsorption fits the pseudosecond order model for the three dyes, and that the adsorption quantity for CV is 125.0 mg g-1, while for MB and AO is 123.3 and 94.6 mg g-1 respectively.
我们展示了一项关于甲酚紫（CV）在水溶液中吸附于超声处理的氧化石墨烯（sGO）的研究。为作比较，我们还展示了在相同条件下亚甲基蓝（MB）和吖啶橙（AO）的吸附结果。吸附剂通过Tour法合成，随后在水和乙醇中洗涤并超声处理，未进行任何还原处理，并通过拉曼、红外、紫外可见、扫描电子显微镜和透射电子显微镜技术进行研究。我们的结果表明，三种染料的吸附均符合准二级模型，CV的吸附量为125.0 mg g-1，而MB和AO的吸附量分别为123.3和94.6 mg g-1。
