摘　　要：针对废旧锌锰电池中的碳棒进行高附加值回收利用,采用改进的Hummers法从废旧锌锰电池中回收制备氧化石墨烯,分别考察了低温、中温和高温的反应时间、高锰酸钾用量、浓硫酸用量及不同干燥方式对制备氧化石墨烯产品的影响。结果表明:以碳棒为原料制备氧化石墨烯是可行的,当石墨粉用量为1 g、高锰酸钾5 g、浓硫酸20 mL、低温反应时间2 h、中温反应时间4 h、高温反应时间30 min时,可制备得到氧化程度较高的氧化石墨烯。The carbon rods of waste Zn-Manganese batteries were recycled with high added value,and the improved Hummers method was used to prepare Graphene Oxide(GO).The effects of reaction times at low,medium and high temperatures,potassium manganese acid dosage,concentrated sulfuric acid dosage and different drying methods on the preparation of graphene oxide were investigated.The results show that it is feasible to prepare graphene oxide with carbon rod as raw material.When the amount of graphite powder is 1 g,potassium permanganate is 5 g,concentrated sulfuric acid dosage is 20 mL,low temperature reaction time 2 h,medium temperature reaction time 4 h,high temperature reaction time 30 min,GO can be prepared with high oxidation degree.
