...Alan Stanley Abstract A simplified biquinoline method was used to determine the readily extractable copper content in a suite of drill-core samples from an area of known economic mineralization [Granduc, British Columbia]. The method gave reproducible results and the data indicate that copper...

... of the biquinoline reagent and copper complex under field conditions, and the fact that biquinoline is specific for copper.Since 1955 the method has been tried on several hundred samples of soil and sediment from various localities in the United States with generally excellent results; the only serious interference...

...L. C. Huff; T. G. Lovering; H. W. Lakin; A. T. Myers Abstract Analytical methods used in geochemical prospecting for Cu were compared by analysis of samples of residual soil collected in duplicate near a Cu-bearing vein at the Malachite mine, Jefferson County, Colorado. In this area barren...

..., 1996 ) has been used as a carrier for intercalated Cu(II) complexes. The <2 μm fraction was obtained by sedimentation. The cation exchange capacity (CEC), determined according to the method suggested by Hendershot & Duquette (1986) was 0.98 mmol Me + /g. Although knowledge...
