| Abstract: | A method of enrichment of cadmium in supplementary materials used in tobacco manufacturing by ion-exchange and determination by FAAS was studied. Strong alkali anion resin was used in the experiment. Sample was digested by the microwave assisted heating. In the application to the analysis of 4 kinds of supplementary material samples, RSD's of analytical results obtained were less than 3. 5%, and results of recovery test were in the range of 96%-104%. |
