摘　　要：In this study,the disposable facial tissues derived carbon aerogels(DFTs-CAs)were synthesized using disposable facial tissues as the raw material for fabricating a sensitive amperometric ascorbic acid(AA)sensor.The experimental results indicated that compared to glassy carbon electrode(GCE)and the popular carbon nanotubes modified GCE(CNTs/GCE),DFTs-CAs modified GCE(DFTs-CAs/GCE)exhibited better electrocatalytic activity(i.e.,lower peak potential and higher peak current)for AA electrooxidation and higher analytical performance for AA determination(i.e.,wider linear range,higher sensitivity and lower detection limit),which could be most likely due to the high density of defective sites and large specific surface area of DFTs-CAs.Especially,the DFTs-CAs/GCE was used for evaluating the AA level in real samples(i.e.,medical injection dose,vitamin C tablets,fresh orange juice and human urine)and the results are satisfactory.
