Method for preparing activated carbon by quickly activating waste coffee grounds with solid zinc chloride

The invention provides a method for preparing activated carbon by quickly activating waste coffee grounds with solid zinc chloride. According to the method, the waste coffee grounds are used as a carbon source and activated by the solid zinc chloride to prepare the activated carbon with good adsorption performance. According to the method, the solid zinc chloride is adopted as an activator, the activation process is simple, the activation time is short, and the method is an efficient and economical preparation method and is suitable for industrial production. 本发明提供了一种固体氯化锌快速活化废弃咖啡渣制备活性炭的方法。该方法以废弃咖啡渣为碳源，经固体氯化锌活化，制备出具有良好的吸附性能的活性炭。该方法活化剂为固体氯化锌，活化过程简单，活化时间短，是一种更高效、经济的制备方法，适合于工业化生产。
