| Abstract: | A method for the determination of high content of tin in a sputtering alloy by FAAS is reported in this paper. The sample is dissolved in an acid mixture of HCI(1 + 1) and HNO_3(1 + 1). Tin is then determined by FAAS at the wavelength of 286. 3nm using fuel-rich flame. The linear relationship between tin concentrations and absorbances holds over the range 0 to 250mg of tin per liter. The sensitivity of the method is found to be 3. l0mg per liter for an absorbance of 1%. A recovery of 100. 1 %~103. 7% is found by the standart addition method and the RSD found in smaller than 3. 5%. |
