| 摘 要： | 以微波为热源，Na2CO3为活化剂，采用化学活化法制备废木屑活性炭（AC）。采用Taguchi法考察了微波辐照功率、辐照时间、活化剂浓度、固液比对活性炭碘吸附值的影响。结果表明，微波辐照功率对活性炭碘吸附值的影响最显著，辐照时间次之，而固液比的影响不显著。优化的工艺参数为微波辐照功率440W、辐照时间9min、Na2CO3浓度15％、固液比1：2．5，该条件下AC的碘吸附值为1230．40mg／g，实验结果验证了Taguchi法的有效性。该条件下制得的AC用于处理印染废水，结果显示，对COD为239．5mg／L废水投加3g／L活性炭，在pH为11时吸附70min，COD的去除率达77．9％。
