以梧桐树叶为原料，采用磷酸活化，微波辐照的方法制备活性炭，设计正交实验以考察微波功率、活化时间、磷酸浓度、液固比等因素对活性炭吸附性能的影响。结果表明，最佳工艺参数为：微波功率640 W，活化时间280 s，液固比7：1（ mL/ g），磷酸浓度为60％。该条件下制备的活性炭的碘值为451.88 mg/ g，亚甲基蓝值为15.1262 mg/ g。用其处理城市生活污水，取得了很好的效果。
以梧桐樹葉為原料，採用燐痠活化，微波輻照的方法製備活性炭，設計正交實驗以攷察微波功率、活化時間、燐痠濃度、液固比等因素對活性炭吸附性能的影響。結果錶明，最佳工藝參數為：微波功率640 W，活化時間280 s，液固比7：1（ mL/ g），燐痠濃度為60％。該條件下製備的活性炭的碘值為451.88 mg/ g，亞甲基藍值為15.1262 mg/ g。用其處理城市生活汙水，取得瞭很好的效果。

Activated carbons were prepared from the Chinese parasol leaves,using phosphoric acid activa-tion and microwave irradiation to get. The influence of microwave power,irradiation time,the concentration of phosphoric acid,liquid-solid ratio,etc. on activated carbon adsorption properties were studied. The re-sults show that the optimal process for preparation are obtained as following:microwave power is 640 W, irradiation time is 280 s,liquid-solid ratio is 7: 1(mL/ g),phosphoric acid concentration is 60% . The io-dine value of activated carbon is 451. 88 mg / g,methylene blue value is 15. 126 2 mg / g. This activated carbons is used to treat municipal wastewater,and the effect of adsorption is satisfactory.
