The concentration of copper in a sample of sea water is determined by anodic stripping voltammetry using the method of standard additions. The analysis of a 50.0-mL sample gives a peak current of 0.886 μA. After adding a 5.00- μL spike of 10.0 mg/L Cu2+, the peak current increases to 2.52 μA. Calculate the µg/L copper in the sample of sea water.
