| Abstract: | Different kinds of graphite tubes and of matrix modifiers have been tested for optimization of operation condition for determination of Al in serum by GFAAS. The effects of different interference ions have been eliminated by adding K2Cr2O7 and Triton X-100 as matrix modifier. The method is suitable for determination of serum of cancer patients. The characteristic mass is 21.15pg/0.0044 A x S. The recovery rate is 104.92. The relative standard deviation is less than 8.17%. The result obtained is satisfactory. |
