Summary: | The present invention provides a method of using microwave to activate waste carbon fiber, including the following steps: (a) mixing a waste carbon fiber and an activating agent with a solvent for preparing a treatment liquid, wherein the carbon fiber/activating agent ratio is in the range from 1:1 to 1:8; (b) subjecting the treatment liquid to microwave irradiation, wherein the microwave power is in the range from 600 W to 1000 W, and the microwave time is in the range from 40 minutes to 60 minutes; and (c) filtering and drying the treatment liquid after microwave irradiation for obtaining an activated carbon fiber. The present invention uses high power microwave irradiation and a high dose of activating agent to evenly and fast provide energy to carbon fiber, thereby capable of fast preparing an activated waste carbon fiber having excellent adsorption ability. |
