Spectrophotometric Determination of Copper

Spectrophotometric Determination of Cu2+ The Problem Branicoda Copper Mine is considering opening up a new mining site. The geologists feel that there might be a lot of copper at this new site. Samples of ores taken from the new site were sent to Water Wagon Laboratories to be tested. The ore samples were recently added to a sulfuric acid solution to bring out the Cu2+ (copper(II) ions) into

Introduction to Spectroscopy: Analysis of Copper Ore

Spectrophotometric Analysis: As discovered in the last lab, a spectrophotometer is an instrument that measures the intensity of a light beam of a given wavelength (color) that passes through a sample. Our machines use wavelengths between 325 and 1100 nm. Light of a given wavelength passes through the sample, hits the detector, and the instrument can calculate the absorbance (A) of the solution
