| Abstract | dc.description.abstract | A preconcentration method based on the adsorption on activated carbon of a binary complex of copper(I) with 2,2’-biquinoline, and subsequent polarographic determination of microamounts of copper has been developed. The adsorbed complex is destroyed by a mixture of acetonitrile and perchloric acid. The free copper ions are measured by differential pulse polarography in a supporting electrolyte of 0.2M potassium thiocyanate. The detection 1imit was found to be 0.33 ng/ml (3a). This method was successfully applied to the determination of copper in sea water. © 1991, Taylor & Francis Group, LLC. All rights reserved. | |
