A trace amount of iron was extracted as the complex with 4,7-diphenyl-1,10-phenanthrolinedisulfonic acid from aqueous solution using finely divided anion and cation exchange resins. The mixed resins were collected on a filter paper as the disk of thin layer. The colored complex in the resin phase was determined with the use of a densitometer at 540 nm. The calibration graph was linear over the range 0.1–0.5 μg of iron(II). The relative standard deviation for 0.5 μg of iron(II) in 50 ml of the test solution was 2.1% (<I>n</I>=5). The method was applied to the trace determination of total iron in water samples.
