碳复合材料传感器性能研究及其应用
目的 建立比色传感器法快速检测食品中痕量Hg2+的含量。方法 合成多级孔碳@壳聚糖(hierarchical porous carbon@chitosan, HPC@CS)-AgNPs复合材料, 加入汞离子后, 催化活性增强, 催化氧化3,3',5,5'-四甲基联苯胺(3,3',5,5'-tetramethylbenzidine, TMB)显色, 实现对汞离子的快速检测。结果 将实验条件优化后, 汞离子在浓度为2×10?8~1×10?6 mol/L的范围内线性关系良好(r=0.99753), 在水样与鱼样的加标回收率为84.4%~103%, 相对标准偏差为2.6%~5.2%。结论 该方法操作简便、精密度和重复性好, 可适用于食品中检测汞离子的含量。
Objective To establish a method for rapid determination of Hg2+ in food by colorimetric sensor. Methods The multistage aperture carbon@chitosan (hierarchical porous carbon@chitosan, HPC@CS)-AgNPs composites were synthesized. After the addition of mercury ions, the catalytic activity was enhanced, and the 3,3',5,5'-tetramethylbenzidine (TMB) was catalyzed and oxidated, realizing the rapid detection of mercury ions. Results After optimizing the experimental conditions, the mercury ions had a good linear relationship in the range of concentrations of 2×10?8-1×10?6 mol/L(r=0.99753). The standard recovery rate of water samples and fish samples were 84.4%-103%, and relative standard deviation was 2.6%-5.2%. Conclusion The method is easy to operate, precise and repeatable, and can be used to detect the content of mercury ions in food.
