AB  - Indirect determination of copper was based on determination of cyanide on working silver electrode. The system was equipped with two injection valves. One for injection of cyanide solution (reagent) and another one for the sample injection (copper solution). Carriers for cyanide and copper were 0.02 mol/L sodium-hydroxide and 0.01 mol/L hydrochloric acid, respectively. The copper determination in such system was severely interfered by the presence of cations forming stable cyano complexes [1]. The interferences were successfully removed off-line by applying appropriate chemical reaction. The most prominent interferants were nickel and zinc. By including the dumper in the FIA system, containing cotton wool soaked in an appropriate solution, nickel and zinc were successfully removed. Interferences from nickel were removed by soaking the wool in the alkaline solution of dimethylglyoxime (DMG) and the zinc was removed by soaking the wool in acidic solution of the p-NIAZOX (7-(4-nitrofenilazo)-8-hydroxyquinoline-5-sulfonic acid) [2]. The method was applied for determination of copper in real samples.
