| 摘 要： | 为实现水环境中微囊藻毒素的高性能检测，利用农业废弃物合成了具导电性能的生物炭颗粒，并将其作为导电材料构建了对微囊藻毒素-LR具电化学免疫检测性能的生物模板电极。实验结果表明：该电极具有很好的电催化性能，在电解液中，能够在短时间（5 min）内有效识别微囊藻毒素-LR的存在；利用差分脉冲伏安法检测发现在0.0~5.0 nmol/L的检测范围内毒素浓度与响应电流值呈线性递减关系，且最低检测浓度为0.2 nmol/L。该电极对各类不相关分子及离子具有抗干扰能力，表明了该方法可应用于对微囊藻毒素-LR污染的快速、特异性检测。

| Abstract: | For the effective detection of microcystin-LR (MCLR) in environmental water, in this study, the biochar particles were prepared from agricultural wastes,and it was utilized for the construction of a biotemplated electrode with electrochemical immunoassay capability toward microcystin-LR by differential pulse voltammetry. It is found that the electrode can identify the presence of microcystin-LR effectively in a short time (5 min), the linear detection range is 0.0-5.0 nmol/L and the lowest detection limit is 0.2 nmol/L. The electrode is also anti-interfere to various unrelated molecules and ions, indicating that the electrode can be used for fast and effective detection of microcystin-LR. |
