Flow injection-hydride generation-infrared spectrophotometric determination of Pb.

A novel analytical technique has been suggested for determination of Pb using formation of PbH(4)(g) by chemical reduction and its subsequent spectrophotometric measurement in IR region, using the peak at 1821.4cm(-1). The range of measurements is 1.0-30.0mgl(-1) using a sample of 1.0ml in flow injection mode. The 3sigma limit of detection is 0.28mgl(-1). The method has been applied to standard reference materials of Waste Water, EU-L-1, lead-base bearing metal 53e and Soil/Sediment #4 as well as soil samples collected from heavy traffic areas in Ankara.
