dc.description.abstract以壳聚糖为保护膜、玻碳为基底,用纳米Au和Fe3O4磁性纳米粒子构建了新型亚硝酸盐(NO2-)传感电极. 实验表明,该传感电极对NO2-有良好的电催化氧化活性,NO2-浓度(5.0×10-6 ~ 2.0×10-3 mol·L-1)与氧化峰电流之间呈良好的线性关系(R = 0.9996),检出限7.1×10-7 mol·L-1, 其灵敏度高、选择性好、重现性好.zh_CN
dc.description.abstractA novel nitrite sensing electrode based on gold nanoparticles and iron oxides (Fe3O4) magnetic nanoparticles was fabricated with chitosan as the protective film on glassy carbon matrix. Experiment results showed that the sensing electrode exhibited good electrocatalytic activity toward oxidation of nitrite, and the oxidation peak current increased linearly with the concentration of nitrite varying from 5.0×10-6 to 2.0×10-3 mol·L-1 (R=0.9996) with a detection limit of 7.1×10-7 mol·L-1 (S/N=3). The sensing electrode exhibited good sensitivity, selectivity and repeatability.zh_CN
