| Abstract: | A simple and rapid method has been proposed for direct determination of Cd, Pb, Cu in marine sediments and suspended matters by graphite furnace atomic absorption spectrometry, using the HNO3-HClO4-HF decomposition. The L'vov platform and matrix modiffer technique were used with peak-area measurement to effectively eliminate the matrix interference usually encountered for Cd, and Pb. Radios of the standard addition curve and the working curve slopes for Cd and Pb in marine sediments and suspended matters were nearly 1.0. Thus, the working curve method can simply be used in the determination. The necessity for performing standard additions on every sample may be omitted. the sensitivities for Pb and Cd using the L'vov platform were higher than those using the tube only by a factor 2. |
