| Abstract: | The impacting factors on the uncertainty in measurement results of Al_2O_3 in soil samples were discussed and the uncertainty was evaluated. EDTA complex-KI replacemen-Zn(Ac)_2 titration method was used for sample pretreatment and determination of Al_2O_3 in soil samples. When concentration of Al_2O_3 is 15.03%, the expanded uncertainty is 0.20% (U_(rel)=1.4%, k=2). |
