Calculating the concentration of Cd and Cu in a water sample by ASV (Anodic Stripping Voltammetry). An interactive exercise.

Abstract

In this exercise, the student must calculate the concentrations of Cd and Cu in a water sample from voltammetric data. These data are randomly generated from analytical data obtained in the lab. The analytical steps are skipped and only numerical data, SAM (Standard Additions Method) graphs and linear fits by the least squares method are presented. The user should calculate the concentrations of the analytes and enter them into the system for their verification. The aim is therefore to learn to use the graphical standard addition graphs to calculate and give the correct expression of the analytical results
