Determination of Copper and Lead in Brass

Determination of Cu and Pb in Brass By:  T.A. Alicia Smith Introduction             In this experiment, four different methods were used in determining the concentration of copper and lead presence in the unknown brass sample #10. Methods of High-performance liquid chromatography (HPLC) and atomic absorbance spectroscopy were used to measure both copper and lead concentration in the unknown brass while the Gravimetric analysis was used solely to determine the lead concentration. The anodic stripping voltammetric method was also used to […]
