Popis:	A procedure for the automated on-line determination of nickel in aquatic samples was developed. It is based upon adsorptive stripping voltammetry of the dimethylglyoxime complex at a thin-mercury film electrode (TMFE) on glassy carbon substrate. The severe problem of reproducibly renewing the TMFE was solved by the choice of an appropriate electrolyte and a special potential program. With the developed procedure automatic on-line nickel determinations are possible over extended periods of time with standard deviations not higher than 5% and down to 1.3 ppb nickel.
