Abstract :
A novel analytical technique has been suggested for determination of Pb using formation of PbH4(g) by chemical reduction and its subsequent spectrophotometric measurement in IR region, using the peak at 1821.4 cm−1. The range of measurements is 1.0–30.0 mg l−1 using a sample of 1.0 ml in flow injection mode. The 3σ limit of detection is 0.28 mg l−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.
