For the first time, lead film electrodes resistant to the action of oxidants commonly used to enhance the catalytic electrochemical response were deposited physically from a gaseous phase on thick film gold substrates and applied in catalytic adsorptive stripping voltammetry (CAdSV). The newly developed multilayer electrodes comprising a glass slide, an adhesive layer of titanium, a gold layer and finally, the working layer of lead were characterized by excellent CAdSV performance. Their sensitivity and reproducibility improved further after thermal pretreatment. The proposed sensor was sensitive (LOD = 0.002 μg L⁻¹; t_acc = 30 s) and the cobalt response was very reproducible (2.3%) and depended linearly on cobalt concentrations within the range of 0.06–1.05 μg L⁻¹.

第一次，从气相以物理方式从气相气相沉积铅膜电极，该电极通常用于增强催化电化学反应，而氧化剂通常用于增强催化电化学反应，并将其应用于催化吸附溶出伏安法（CAdSV）。新开发的多层电极包括玻璃载玻片，钛的粘合层，金层，最后是铅的工作层，具有出色的CAdSV性能。热处理后，它们的灵敏度和重现性进一步提高。拟议的传感器灵敏（LOD = 0.002μgL ^-1；t _acc  = 30 s），钴响应非常可重现（2.3％），并且线性依赖于0.06-1.05μgL范围内的钴浓度^-1。
