摘要
A new flow injection procedure for an assay of Fe(III) by using salicylate obtained from antipyretic powder, which is a cheap and easily available reagent, is proposed. A red complex was continuously monitored by a laboratory-made green LED colorimeter. A linear calibration was obtained in the range of 1-20 mg Fe l(-1) with a detection limit of 0.5 mg Fe l(-1) and R.S.D.s of 1.4-5.4% (n = 3, for 1-20 mg Fe l(-1)). The new procedure was applied to assay iron contents in pharmaceutical preparations. The results were in good agreement with those of the USP standard method. (C) 2004 Published by Elsevier B.V.
