Explain and determine the concentration of cadmium

Reference no: EM13157902

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, 5.00 ?L of a 1000.0 ?g/mL Cd standard was added to 10.0 mL of solution. The following data were obtained: Absorbance of reagent blank = 0.045 Absorbance of sample = 0.556 Absorbance of sample plus addition = 0.881 What was the concentration of the cadmium in the waste stream sample?
