Abstract:Extraction process of chlorophyll from the microwave radiated filter mud was investigated. The best procedure was as follows: after adding 5 mL of 60% alcohol to dissolve 5 g of dried filter mud, the mixture was pretreated by microwave, and then extracted for 30 min by 50 mL of 95% alcohol at 60 ℃. Under the above-mention conditions, the chlorophyll content reached 45 mg/mL, which was higher than that by traditional method (23.86 mg∕mL). And the extraction time was shorter than that of the traditional method (4~12 h).
