| High specific area activated carbon was successfully made from waste foam polystyrene (WFPS) through sulfonation-charing, and then activation by KOH or H3PO4.The activated agent of different kinds and its ration, the activated temperature, the activated time; adsorption properties of HSAAC have been investigated. Base on these, the technologic methods and conditions of controlling structure and properties of HSAAC had been established. Experimental results show that the best technologic conditions of sulfonation-charing are that the ratio of sulfuric acid and WFPS is 2, dipping time is 150 min, the charing temperature is 350℃, and charing time is 2h. In this situation, the charing yield is about 82.01%. It has been shown that the most suitable conditions for activation are as follows: temperature of 700 ℃, a ratio of KOH and raw material of 2, and 150 min of heating time.The analysis results of the activated carbon are that specific area reaches around 1981.5 m2/g, the iodine adsorption value is 1400.0 mg/g, methylene blue adsorption value isl30.9 ml/g, total porous is 1.38 ml/g, micro porous is 1.02ml/g, the pore diameter distribution is from 0.5nm to 2.5nm. H3PO-4 is used to the activated agent too. Experimental results show that the result of activated is not better than KOH, and the surfaces only 1203.95 m2/g. The morphology of HSAAC was observed by scanning electric microscope. The specific area and pore structure of the HSAAC were determined by adsorption method of nitrogen at low temperature. The relation between specific capacitance of the HSAAC and its specific surface area and pore structure were discussed. Experiment results show that this activated carbon has the capability of adsorbing some metal ion.Experiment results show that the structure and performance of activated carbon are influenced mainly by amount of activating agent, activating temperature and activating time. The yield of activated carbon decreases with the increase of KOH, activating temperature and...
