| Abstract: | The atomization behavior of V(V) has been studied in standard graphite tube, pyrolytic coated and totally pyrolytic graphite tube. A method for direct determination of V(V)in drainage sediments by graphite furnace atomic absorption spectrometry with totally pyrolytic glaphite tube and ammonium salt of EDTA as a matrix modifier was described. There was no interference up to 0. 3mol/L of HCIO_4 with 0. 25% ammonium salt of EDTA in the determination of V. The characteristic mass of V is 61 pg/0. 0044A. |
