Determining Trace Metals by the Ring‐Oven Technique—Part 1 : Copper, Cadmium, and Zinc

Abstract

An analytical scheme has been developed for the separation and concentration of copper, cadmium, and zinc from waters. The ring–oven technique is employed for the final concentration step and measurement of the isolated species. Detection of concentrations of these metals well below the maximum permissible concentration is possible with this technique. It is anticipated that this procedure will be useful in field studies and as a screening device to determine compliance with standards.
