摘要
A method of measuring the concentration of metal ions in a sample comprising the steps of: providing a sample comprising a nonpolar, liquid hydrocarbon, suspected of containing a metal ion; adding a dye such as a spirobenzopyran dye or bathocuproine and a reducing agent to the sample; wherein the dye forms a complex with the metal ion; wherein the complex has a spectral shift in light absorbance relative to the dye; observing the spectral shift; and calculating the concentration of the metal ion in the sample.
