Fe(III)와 Xylenol orange의 反應에 對한 分光光度法的 硏究 = Spectrophotometric Study of the Reaction of Iron(III) with Xylenol Orange

다국어 초록 (Multilingual Abstract)

The reaction between iron(III) and Xylenol Orange (XO or H_6A) has been investigated spectrophotometrically.
It has been established that iron (III) and XO form two complexes with compositions iron (III): XO=2:1 and 1:1. The 2:1 complex is stable in acidic or alkaline media containing excess of iron (III)), and 1:1 complex is stable in slightly acidic medium containing excess of XO. The absorption maxima are at 590nm(2:1) and 500nm (1:1), the molar absorptivities being 3,18±.04×10⁴and 1.32±.03×10⁴respectively. The stability constants of two complexes studied by varying pH are logβ_21= 18.69±0.08, logβ_212=42.08±0.09, logβ_11=4.27±0.04 and logβ_115=34.47±0.07
