| Abstract: | The matrix modification,germanium ashing and atomization temperature,and the interference of six coexistent ionic species have been investigated,A mixture of strontium and ammonium nitrate has been used as the matrix modifier.As compared with other modifiers,the above modifier provides some improvement in the sensitivity and selectivity of the determination of germanium by platform GFAAS.The method can be used directly for the analysis of blood samples without preliminary digestion and separation. |
