Abstract
Iron(III) is extracted into methyl isobutyl ketone (MIBK) as a complex with sodium dibenzyldithiocarbamate (DBDTC) in the pH range 2 to 6. The extraction was used for the determination of iron by atomic absorption spectrometry. An aliquot of sample solution containing less than 40 μg of iron is taken, the pH is adjusted to 2 with 6 N sulfuric acid or 6 N ammonia water, and 10 ml of DBDTC solution (0.5 %) is added. The solution is diluted to 50 ml with water, and shaked with 10.0 ml of MIBK for 3 min. The MIBK extract is introduced into an air-acetylene flame and the absorbance is measured at 248.3 nm.By this method, (140) μg of iron could be determined accurately. The tolerance limits for various ions were also determined. The proposed method was applied to the determination of micro amounts of iron in tap waters and waste waters.
