The best pre-concentration was achieved at pH 6.9 over 5 min and the bestip in the measuring cell was obtained at pH 1.5 using ΔE = 100 mV and a scan rate of 40 mV/s. Under these conditions detection limits (10 σ) of 15 ng/ ml were obtained. The method was applied to different beverages without the need for prior separation.||URI:||http://hdl.handle.net/10553/49127||ISSN:||0016-1152||DOI:||10.1007/BF00556910||Source:||Fresenius' Zeitschrift für Analytische Chemie [ISSN 0016-1152], v. 329, p. 756-759|
