摘要：

A method for the on-line removal of dissolved oxygen has been developed and applied to the determination of metals by anodic stripping voltammetry in flowing solutions. The removal of oxygen results from a photochemical reaction between the supporting electrolyte and oxygen, induced by ultraviolet light directed into the detector flow cell. Organic acids such as citric, formic, and oxalic acids have been used as supporting electrolytes. Citric acid was found to he the most efficient oxygen scavenger. The removal of oxygen with this acid was also more efficient than conventional removal with nitrogen gas. The determination of Cu, Cd, and Pb used to demonstrate the method.
