THE SPECTROPHOTOMETRIC DETERMINATION

The purpose of this experiment is to determine: (1) the percentage of copper in a copper-clad penny and (2) the thickness of the copper layer on the copper-clad penny. These analyses will employ spectrophotometric techniques. BACKGROUND Pennies minted in the United States since 1982 no longer contain pure copper metal.

Using Spectrophotometer To Determine Concentration (UV/VIS)

When using a spectrophotometer to determine concentration of a sample solution of unknown concentration by UV/VIS spectroscopy, a calibration line must first be created. This is done by measuring the light absorption of several standard solutions of different, known concentrations at a predefined, fixed wavelength.

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors..
