Abstract:An FI-KR non-separated method coupled with FAAS for the determination of Fe(Ⅱ) and Fe(Ⅲ) was developed. With 60 s of sampling at a flow rate of 6.0 mL·min-1, EF of 41 for Fe(Ⅲ) and 9 for Fe(Ⅱ) were obtained. The precision(RSD,n=11) for Fe(Ⅲ) and Fe(Ⅱ) was 2.3% and 3.1% at the 0.04 mg·L-1 level respectively. When 0.1 ‰φ TEA was used as masking reagent, the recovery rate for Fe(Ⅲ) and Fe(Ⅱ) was from 97% to 101 % and from 96% to 100% respectively.
