33. The atomic absorption method was used to determine trace amounts of copper in natural water. When measuring the absorbance of the solution of the control experiment and the standard solution, the following results were obtained:
cCu, μg/ml 0.0
A 0.040 0.050 0.035 0.045 0.040
cCu, μg/ml 1.0
A 0.110 0.100 0.105 0.108 0.102
What information can be gleaned from these results?
