yes, the use of electrochemical methods is an interesting alternative. but for more accurate results ICP-MS is good.

In the hands of an expert, modern electrochemical methods are very powerful techniques

Lawrence Olusegun Ajala it depends on which electrochemical method you use for the determination: potentiometry or voltammetry. And within each one, the characteristics of the electrode used will have a lot to do, however, in general, electrochemical methods are valid for this application as long as they are implemented correctly. I particularly recommend voltammetric anodic stripping. Regards.

It depends on the number and the suite of analytes you try to measure. Following are some points to consider:

- ICPMS is a very sensitive multi-element technique whereas electrochemical techniques are usually single analyte. Therefore, in terms of efficiency, handling interferences, etc., they are not nearly comparable as the number of analytes increases. If you are interested in one or two metals, it may be a practical approach.
