摘要
使用水热法制备了Ag2S-MWCNTs纳米复合材料,表征了该纳米材料的形貌和化学组成。使用此材料构建了Ag2S-MWCNTs/GCE电化学传感器,研究了其电化学性能。该传感器检测亚硝酸盐的线性范围为3.3~4.8×10^5μmol/L,检出限为1.1μmol/L。该电化学传感器具有构建简单、灵敏度高、稳定性好、成本低等优点。
Ag2S-MWCNTs nanocomposites were prepared with hydrothermal method.The morphology and chemical composition of the nanocomposites were characterized by SEM and EDS.An electrochemical sensor for nitrate was constructed and its related electrochemical properties investigated.The linear range was 3.3~4.8×10^5μmol/L and the detection limit 1.1μmol/L.The electrochemical sensor has such advantages as simple construction,high sensitivity,high stability and low cost.
