Rp. Pantaler et al., RAPID SEMIQUANTITATIVE DETERMINATION OF IRON IN POTABLE WATER USING AN INDICATOR PAPER, Journal of analytical chemistry, 52(4), 1997, pp. 341-343
A rapid test procedure is proposed for the detection and semiquantitat
ive determination of total iron and weakly bound iron species with the
use of an indicator paper. Phenylfluorone was used as the indicator.
The detection limit of iron (II, III) was found to be 0.2 mg/L at a fi
ducial probability of 0.95.
