This paper reports the light absorption(between 400-800 m, u) of py rocatechol-ferric iron solutions in the range of pH 2-12, and the complexes found by means of Job's continuous variation method with "pectrophotometer(Unicam, S.P.500).It is found that there are five completes in the solutions studied, among whit0h two(Ⅰ, Ⅲ) have not yet been reported previously.
