Abstract: A sensor for detecting lead in an aqueous solution includes a copper working electrode, a counter electrode, a power supply for applying underpotential deposition of lead onto the copper electrode, a measuring device for providing measurement of a hydrogen evolution reaction (HER) current on the Pbupd-modified electrode, and a controller configured to correlate the degree of suppression of the HER current to Pbupd coverage to determine the lead coverage and lead concentration of the solution.

Abstract: A process for production of metal(s) by molten-salt electrolysis includes direct non-carbothermic chlorinating of ore containing metal oxide(s) to produce metal chloride(s); and electrolysis of molten salt(s) of the metal chloride(s) for electrowinning of metal(s) product.

Abstract: A sensor for detecting lead in an aqueous solution includes a copper working electrode, a counter electrode, a power supply for applying underpotential deposition of lead onto the copper electrode from the aqueous solution, a measuring device for providing measurement of a hydrogen evolution reaction (HER) current on the Pbupd-modified electrode, and a means for correlating the degree of suppression of the HER current to Pbupd coverage to determine the lead coverage and lead concentration of the solution.
