Description
In the precipitation of trace heavy metals as hydroxides, iron(III) hydroxide is usually used as collector. However, information on the precipitation of microgram amounts of iron as hydroxide is so scanty that this work was undertaken. Ten to 100μg of iron(III) could be precipitated almost quantitatively with 5.0 mg of aluminum(III) from 100 ml of sample solutions in the range of pH 6.5 to 8.5. The iron was determined photometrically with 1, 10-phenan throline. Diverse ions, such as fluoride, phosphate, tartrate, citrate and EDTA interfered with the precipitation of iron. However, the interference of 0.1 mmol of tartrate, citrate or EDTA could be eliminated by adding 1.0 g of ammonium peroxodisulfate to 100 ml of sample and boiling the solution for about 30 min at 0.05 M sulfuric acid.
