The preparation of metallic lead films by electrochemical deposition was reported. Although primary deposits at fresh state (also referred to as fresh deposits) were indeed metallic lead films, the fresh lead films could be rapidly oxidized to lead oxide in air. To obtain long stable metallic lead films, the key process is how to prevent the oxidization of fresh lead films. Our studies indicate that the washing of fresh metallic lead films in absolute alcohol is a simple but effective method to protect the lead films from the oxidization for an extended period of more than 20 days.

In this paper, we developed a simple and effective method to fabricate lead oxide plate films by electrochemical deposition. The electrolyte was lead nitrate aqueous solution with or without Cl- ions. Stainless steel plate was employed as both cathode and substrate, and a graphite plate as anode. We found the optimal current density of synthesizing lead oxide plate films is 10-25mA/cm2 when there were no Cl- ions in the electrolyte. If equal Cl- ions were added in lead nitrate aqueous solution, the optimal current density of synthesizing lead oxide plate films is less than 10mA/cm2. The as-prepared lead oxide plate films have orthorhombic crystals structure.

The Impact

In this paper, we report a simple method to fabricate lead oxide nanostructure by electrochemical deposition. In our experiment, the electrolyte was lead nitrate aqueous solution containing some drops of concentrated hydrochloric acid. ITO was employed as both cathode and substrate. The controlled current that was supplied by a direct current power supply passed through the electrolyte to deposit the PbO nanostructure on the surface of ITO at room temperature. The morphology of lead oxide was affected by the concentration of electrolyte. So the impact of the electrolyte concentration on the synthesis of PbO nanostructure was discussed. The as-synthesized products were characterized by scanning electron microscopy and X-ray diffraction. Our results indicate that different PbO nanostructure could be formatted with different electrolyte concentration at current densities in the range of 5-10mA/cm2.

Abstract Lead contamination in drinking water can pose serious health risks to humans, and can often go undetected as a result of corrosion of lead infrastructure installed in buildings constructed prior to 1986. Thus, there is an unmet need for timely, cost-effective, and onsite monitoring of lead in drinking water. Here, we have designed a four-electrode system to reliably respond to electrodeposited lead oxide that provides a near real-time indication of lead presence. To better understand this detection mechanism, we investigated the temporal and spatial electrochemical deposition of lead using potential response data, scanning electron microscopy (SEM), fractal dimension (fD), and COMSOL Multiphysics® finite element analysis. Our results suggest that the deposition of lead oxide on the sensor is diffusion limited. Such fundamental understanding of the detection mechanism is critical to improve and shorten the detection time of the sensor. We used this information to improve the detection time and reliability of the signal by reducing the electrode gap distance and agitating the solution. This study provides a path for further optimization of a continuous electrochemical sensor for onsite monitoring of lead in drinking water.

A simple and effective electrochemical deposition method to fabricate lead oxide micro-octahedrons is reported. Unlike previous reports in which the current densities of electrochemical deposition were normally not more than 5 mA/cm2 and resulted in the deposition of lead flakes, the current densities in our process were improved to more than 15 mA/cm2 which results in the deposition of lead oxide micro-octahedrons. Our results indicated that well-shaped lead oxide micro-octahedrons could form at current densities in the range of 15–25 mA/cm2.

The incidence of Industrial Lead Poisoning is closely related to those sections of the manufactures which involve the production of dust. In white-lead works, paint-grinding shops, litharge grinding, electrical accumulator works, etc., the dust takes the form of minute particles of the special compound of lead manipulated by the workman. In smelting, desilverising, trimming metals and in file cutting, finely divided metallic lead, or a lead oxide, is present in the workshop air.
