Use of thiosemicarbazide as masking agent for the direct determination of bismuth in copper by atomic-absorption spectrometry with hydride generation.
A simple atomic-absorption method for determining trace bismuth in copper metal is described. Interference from the matrix is eliminated by masking copper with thiosemicarbazide in acidic solution.
