Özet

An enrichment method is described for the determination of nickel in urine by flame atomic absorption spectrometry after preconcentration with ammonium pyrrolidine dithiocarbamate on activated carbon. The recoveries are above 90 %. The factors affecting recoveries, such as pH, amounts of activated carbon and complexing reagent, and the contact times, were also studied. The calibration graph was rectilinear for the range 2.4-80 mu g l(-1). The relative standard deviation of the measurement was 3 % for nickel at a concentration of 20 mu gl(-1) (n=9). The detection limit of the method was 0.75 mu g l(-1) when 500 ml urine was used.
