We suggest this research to find the better complexation's pH of [Fe(o-fen)3]2+ complex. The literature says only that this complex is quantitative since pH 2,0 until 9,0. We verify that at pH 9,2 the complex has the largest absorbance, showing that it is the largest pH complexation.We conclude that 9,2 is the ideal pH for the complexation of Fe(lI) with 1, 10-phenantroline, when this complex is free of interferents.
