| Abstract: | The trace As in the textile and leather was determined by hydride generation and atomic fluorescence spectrometry. The effects of operating conditions, concentrations of reductant, medium and acidity and coexisting elements on the results were studied. The results obtained under optimum conditions show the detection limit of 7.8 ng/g, the relative standard deviation is less than 3% ,and the addition recovery of between 97% and 105%. |
