The active carbon discarded after the cleaning of 10g step 1 according to solid-to-liquid ratio is that be added to concentration be 0.08 to 10:30 g/mL by step 2
Cu (the NO of mmol/mL3)2In solution, power be 1200W ultrasonic wave handle 80min at room temperature, then proceed to be in revolving speed
220 r/min stir 1.5 h；According to Cu (NO after stirring 1.5h3)2Solution and NaHCO3Liquor capacity ratio is that 1:1 addition concentration is
The NaHCO of 0.1mmol/mL3Solution, then stirs 1h in the case where revolving speed is the magnetic stirring apparatus of 160r/min, and filtering, filtrate are used
Distilled water and ethyl alcohol wash repeatedly, and 12h is dried at 105 DEG C and dries to obtain material drying；
Step 3, the material drying for obtaining step 2 are 1:25g/W according to drying amount of substance and microwave power ratio, in maturing temperature
10min is roasted under the conditions of being 400 DEG C obtains Activated Carbon with Cu.
The absorption methylene blue value of Activated Carbon with Cu through above-mentioned steps preparation is 150 mg/g.
In conjunction with attached drawing, the embodiment of the present invention is explained in detail above, but the present invention is not limited to above-mentioned
Embodiment within the knowledge of a person skilled in the art can also be before not departing from present inventive concept
Put that various changes can be made.
