Abstract A simple flow injection method is proposed for the determination of nickel by its
complexation with ammonium 2-amino-cyclohexene dithiocarbamate (AACD). The dark red
complex can be detected by spectrophotometric determination at 535 nm. The FIA factors
that influence on sensitivity were optimized by factorial design analysis. The model of
absorbance vs. these factors was constructed and the correlation of these factors with each
other was studied. Nickel can be determined as low as 0.007 μg/ml and Beer's law was ...
