| Abstract: | The GFAAS method for Tin determination from environmental air samples has been studied with HNO3 and H2O2 digestion. Mercury metal solution and Ammonium phosphate monobasic soiution were used as the matrix modifier for coating graphite tube. The detection limit of this method is 3.56μg/L （ in solution） , and the relative recovery rate for spikes in soil matrices varied among 90.6% - 102%. |
