| dc.description | Flow injection (FI) methodology, using diffuse reflectance in the visible region of the spectrum, for the analysis of nickel, precipitated in the form of dimethylglyoximate, is presented. A reflectance cell, constructed in polytetrafluoroethylene, using a LED (light emitting diode) as light source and a LDR (light dependent resistor) as detector, is described. The analytical signal (S) correlates with nickel concentration (C) between 1.6 × 10-4 and 6.6 × 10-4 mol L-1. This correlation is described by the equation S = -1.108 + 3.314 × 104C - 2.081 × 107C2 (r = 0.9996). The experimentally observed limit of detection is about 1.3 × 10-4 mol L-1, as in lower concentrations the formation of precipitate is not observed. The experimental quantitation limit is about 1.6 × 10-4 mol L-1. The mean R.S.D. (relative standard deviation) is about 2.7%. Samples containing nickel were analyzed and the results obtained in this method were compared with those of other methods using the statistical Student's t-test. © 2006 Elsevier B.V.
