| Abstract: | This paper reports the best experimental conditions of using graphitefurnace atomic absorptiometry in acid medium measuring trace chromium in animal tis-sue. It systematically explains the choice of digestives,the control of digestion period.acidlty of Sample and coexisting elements'effect.Experiment results show that HNO_3HCIO_4 is better than HNO_3-HCI-H_2O_2 in digesting animal tissue sample. |
