Atomic absorption spectrometry was used with the method of standard additions to determine the concentration of cadmium in a sample of an industrial waste stream. For the addition, 10.0 μL of a 1000.0 μg/mL Cd standard was added to 10.0 mL of solution. The following data were obtained: Absorbance of reagent blank = 0.041 Absorbance of sample = 0.476 Absorbance of sample plus addition = 0.821 What was the concentration of the cadmium in the waste stream sample?Later, the analyst...
