520 |a"This report describes a method for the determination of low concentrations of lead in water samples. The method is based on the application of atomic absorption spectrophotometry using a Zeeman modulated tungsten ribbon furnace. Analytical interferences are eliminated by the addition of ammonium tartrate-nickel [II] nitrate to the samples to act as a matrix modifier and adjust the pH. The results show the superior performance of this modifier over other types used conventionally. A detection limit of 1 ppb with a relative standard deviation of less than 10% was achieved when a multiple injection procedure is used, a detection limit as low as 0.1 ppb can be obtained. The method requires simple instrumentation and is economical and efficient for the determination of lead in variety of water samples"--Abstract.
