摘　　要：以天然植物的果皮为原料,通过水热法制备冬瓜皮衍生碳气凝胶,并将其应用于处理含Pb(Ⅱ)模拟废水。采用扫描电子显微镜等仪器对冬瓜皮衍生碳气凝胶的结构和性能进行表征。同时,研究了pH值、吸附时间、吸附剂用量等因素对Pb(Ⅱ)去除率的影响。结果表明,采用煅烧温度为800℃制备的碳气凝胶,当pH为6.0,吸附时间为10 h时,去除率达到94%,能有效处理含Pb(Ⅱ)废水。The wintermelon peel-derived carbon aerogel have been successfully synthesized through a facile hydrothermal method using the natural vegetable＇s peel as the source material. The morphology and structure properties of the obtained sample were examined by means of scanning electron microscope（ SEM） etc methods. In addition,the adsorption properties of the sample were evaluated by the removal rate of Pb（ Ⅱ）. The effects of p H,adsorption time and adsorbent dosage on the removal efficiency were also studied. The results showed that using the carbon aerogel sample when calcination temperature is800 ℃,pH is 6. 0,adsorption time is 10 h,the Pb（ Ⅱ） removing rate can reach 94%.
