PY - 2021 DA - 2021/02/05 TI - Poly(1,5-Diaminonaphthalene)-Modified Screen-Printed Device for Electrochemical Lead Ion Sensing SP - 6637316 VL - 2021 AB - Poly(1,5-diaminonaphthalene) has been electropolymerized on the screen-printed device with a three-electrode configuration. The modified electrodes have been developed as the new electrode for electrochemical determination of trace levels of lead ions (Pb²⁺）。聚（1,5-二氨基萘）膜防止Pb的沉积²⁺由于聚合物链上的胺和仲氨基，进入裸碳丝网印刷电极的表面缺陷并具有对重金属离子的敏感性。施用方波阳极溶出伏安法检测PB²⁺离子，显示尖锐的剥离峰，线性范围为0.5  μ.G·L.^-15.0  μ.G·L.^-1（ R. 2 = 0.9929. ）。发现检测限为0.30  μ.G·L.^-1。传感器被应用于PB的分析²⁺在自来水样本基质中，结果令人满意。SN - 0730-6679 UR - https://doi.org/10.1155/2021/6637316 Do - 10.1155 / 2021/6637316 JF - 高分子技术PB - Hindawi KW - ER -
