摘　　要：以光合竹为原料,研究了其制备活性炭的工艺条件,考察了活化剂浓度、固液比、活化时间以及活化温度等因素对活性炭碘吸附值、亚甲基蓝吸附值的影响。实验结果表明,用化学法制备光合竹活性炭的最佳工艺参数为:以Zn Cl2为活化剂,Zn Cl2浓度为5 mol/L,活化剂浸渍时间为2 h,固液比为1∶4,活化时间为60 min,活化温度为500℃。在此工艺条件下所制备活性炭得率为48.8%,亚甲基蓝吸附值为197.14 mg/g,碘吸附值为1 034.30 mg/g,样品质量指标接近净化用活性炭标准。By means of photosynthetic bamboo as raw materials,the preparation of its activated carbon has been studied. The influences of the activator concentration, solid-liquid ratio, activation time, activation temperature and other factors on the adsorption values of iodine and methylene blue are investigated. The results show that, the opti- mum technical parameters of photosynthetic bamboo activated carbon prepared by chemical method are as below, ZnCl2 used as activator, concentration of ZnCl2 is 5 tool/L, activator immersion time 2 hours, solid-liquid ratio 1： 4, activation time 60 min, and activation temperature 500 ℃. Under these technical conditions,the yield of activated carbon prepared is 48.8%, methylene blue adsorption value and iodine adsorption value of the prepared activated carbon are 197.14 mg/g and 1 034.30 mg/g, respectively. The quality indexes of the samples are close to the activated carbon standard for water purification.
