| Abstract: | he vapor collection and pulsed sampling technique has been developed for determination of antimony in ores by flow injection-hydride generation-atomic fluorescence spectrometry.Experimental conditions and manifold parameters were investigated in detail.The proposed method is rapid and effective,with a detection limit of 0.19ng/ml of Sb,prccision of RSD=5.1%for 8ng/ml of Sb(n=12),and a sampling rate of 120 samples per hour.Analytical re-sults of standard reference materials are in good agreement with certified values. |
