Abstract
A spectrophotometric flow injection procedure for the determination of lead is described. The procedure is based on measurement of absorbanc e from the colour produced by the reaction of lead with sodium sulfide in the presence of ammonia. Results are presented for lead at a sampl e throughput of 60 h(-1) and repeatability is 1.5% at 1000 mg/dl. The method is well demonstrated by analyzing lead in lead-ores which were pre-determined by using atomic absorption spectroscopy.
