Nedeltcheva T. Voltammetric determination of lead, cadmium and copper traces in ammonium fluoride. Anal Bioanal Chem. 1996;354(3):370-1.
A rapid and precise voltammetric method for the determination of traces of Pb, Cd and Cu in NH(4)F has been developed based on the capability of boric acid to mask fluoride ions and on the measurement of the analyte signals of the blank and the sample in the same solution.
