Abstract

In this paper, the condition of color reaction of a new reagent 2-(2-imidazolylazo)-5-diethylamino phenol(IZAPN) with Fe 3+ is reported. Results show that the IZAPN reacts with Fe 3+ to form a stable purple complex(1∶3) in the buffer solution of HAc-NaAc(pH5 0).The wavelength of absorption maximum and the apparent molar absorptivity are 590nm and 3 56×10 4L·mol -1 ·cm -1 , respectively. Beer's law is obeyed in the range of 0-0 8mgFe 3+ /L. The method has been applied to the direct determination of iron in pure aluminium and aluminium alloy with satisfactory results. The recovery of standard addition is 100 3%-100 6% with precision of 1 6%-3 9% RSD(n=6).
