The determination of copper in the presence of humic acid and osalic acid using anodic srripping voltammetn- (ASV) at the graphite electrode modified with a copper complesing agent, l-phenyl-3methyl-+octanoylpyrazol-5-on. and a Nafion film is described. The validit). of voltammetric criteria for the
The determination and speciation of copper at a carbon paste electrode modified with Dowex 5OW-8X cation-exchange resin was investigated in model and real samples. With this procedure free metal ions and labile complexes can be measured which dissociate during the time scale of the chemical accumula
Surface-enhanced Raman scattering (SERS) of Ct.05 M pyridine/lO-s M CuCl,/O.l M KCl/water/Ag electrode and 0.05 M pyridine/O. I M KCl/water/Cu electrode systems was studied at T=24 and 45 "C. At T= 24°C a very small amount of IO-' M Cu ions could stabilize the large amount of surface Ag adatoms and
