Copper was determined in a river water sample by atomic absorption spectrometry and the method of standard additions. For the addition, 100.0 µL of a 1000.0 µg/mL Cu standard was added to 100.0 mL of solution. The following data were obtained: Absorbance of reagent blank = 0.020 Absorbance of sample = 0.520 Absorbance of sample plus addition – blank = 1.020 Calculate the copper concentration in the sample.
