采用微波加热再生废弃针剂用活性炭，通过响应曲面法中模型的优化设计和分析，研究了再生过程中的3个影响因子（再生温度、再生时间以及物料厚度）对所再生活性炭亚甲基蓝值和得率的影响，并通过方差分析（ANOVA）研究了各个实验因子或交互作用对活性炭性能的影响。得到实验优化工艺条件为：再生温度700℃，再生时间18min，物料厚度20mm，所再生活性炭亚甲基蓝值和得率分别为187.5mg/g，65.20%。此外，再生活性炭比表面积高达962m2/g，总孔体积为1.02mL/g，平均孔径为4.27nm。

Regeneration of spent activated carbon for the refinement of injection by microwave heating was mainly studied using response surface methodology for optimal design and analysis. The effects of three regeneration variables,including regeneration temperature,regeneration time and material thickness,on the adsorption properties and yield of activated carbon were investigated with the analysis of variance (ANOVA),and the significant factors on each experimental design response were identified.The optimal condition has been identified to be the regeneration temperature of 700℃, regeneration time of 18 min and material thickness of 20mm. Under above condition,methylene blue adsorption value and yield of activated carbon are 187.5 mg/g and 65.20%,respectively. Furthermore, the BET surface area,total pore volume and average pore diameter of regenerated activated carbon are 962m2/g,1.02mL/g and 4.27nm respectively.
