摘要:

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.
