摘　　要：根据GB/T 12496.10-1999测定被活性炭吸附过后的亚甲基蓝溶液的吸光度来检测活性炭的吸附性能,根据吸附结果得出最佳工艺条件:磷酸法为磷酸浓度60%,活化时间120 min,活化温度500℃,收率为46.25%,亚甲基蓝吸附量为:12.0 m L/0.1g。KOH/NaOH法制备活性炭最佳条件为炭化时间60 min,活化温度700℃,收率为11.66%,亚甲基蓝吸附量为11.5 m L/0.1g。结果表明磷酸法收率高,吸附效果理想,是油茶饼粕活性炭较好的制备方法。According to GB/T 12496.10-1999, it is concluded that the best process conditions： phosphoric acid method for phosphoric acid concentration 60 %, activation time, 120 min, activation temperature of 500℃. The yield was 46.25 %, and the adsorption of methylene blue was： 12.0 mL/0.1g. KOH/NaOH optimum condition for the preparation of activated carbon for 60 min carbonization time, activation temperature of 700 ℃. The yield was 11.66%, and the adsorption of methylene blue was 11.5 mL/0.1g. The results show that the high efficiency of phosphoric acid and the ideal of adsorption effect are the better preparation methods for activated carbon of camellia meal.
