| Abstract: | The method of determining Ph,Cd and Fe in the inner bladder of magnetic mug by flame atomic absorption spectrophotometry was studied. The samples were broken to pieces,and dissolved by mixtures of nitric acid and perchloric acid. The method is simple, fast and sensitive, and has little interference. It also has good precision and accuracy. The relative standard deviations of Ph, Cd and Fe are 3. 99%, 10. 7% and 0. 9%, respectively, and the rates recovery are 100. 61 %, 101. 18% and 102.41 %, respectively. |
