ABSTRACT
Differential electrolytic potentiometry (DEP) was coupled with the sequential injection/flow injection analysis (SIA/FIA) for the quantitative determination of cyanide in aqueous media. The univariate method was used to optimize the reagent concentration, the current density, the flow rate, and the delay time. A solution of nickel (II) was used as a reagent and silver amalgam electrodes were used as an indicating system. Cyanide was determined in the concentration range of 6-39 �g�mL-1 with a correlation coefficient of 0.999. The detection limit was found to be 0.31 �g�mL-1 with a RSD of 2.5% (n = 5) and the sampling frequency of 45 samples per hour.
