Use of a liquid ion-exchanger in the solvent extraction and atomic-absorption determination of trace copper in waters.
Copper in the 10-100 ppM range has been determined by a solvent extraction and atomic-absorption procedure involving the use of the liquid ion-exchanger Amberlite LA 2 in thiocyanate form. The procedure is rapid and gives results of good precision, and uses stable reagents and standard instrumentation.
