“…The RSD values (n = 5) of the present work were 2.4% for 5 μg L -1 vanadium and 2.8% for 50 μg L -1 iron, respectively. The repeatability was comparable to that of the previous SILFA method, 23 whose RSD values (n = 5) were 2.2 for 1 μg L -1 vanadium and 2.3% for 10 μg L -1 iron, respectively. However, the sensitivities of the proposed method for the successive determination of vanadium and iron were better than those of a catalytic spectrophotometric method for the simultaneous determination of mg L -1 levels of vanadium and iron.…”

“…In the presence of 0.015 mol L -1 diphosphate in the RS1, 400 μg L -1 iron was tolerable for the determination of 1 μg L -1 vanadium. for vanadium, 2.20 μg L -1 for iron) were higher than those obtained with previous FIA methods (e.g., 0.01 μg L -1 for vanadium 9 and 0.05 μg L -1 for iron 13 ) and with a previous SILFA method 23 (0.052 μg L -1 for vanadium and 0.55 μg L -1 for iron). The RSD values (n = 5) of the present work were 2.4% for 5 μg L -1 vanadium and 2.8% for 50 μg L -1 iron, respectively.…”
