This work deals of spectroscopy characterization of the 1,4-bis(3-carboxy-3-oxo-prop-1-enil)benzene acid, a possible metal ion complexant compound. An aqueous solution of the title compound was irradiated using a 80W mercury lamp and the photodegradation was followed by UV/VIS absorption spectra. The molar extinction coefficient determined was 36,457 L mol-1 cm-1 and degradation rate observed was 5.2x10-7 mol L-1 min-1, when the sample was irradiated in a quartz cuvette of 10mm optical path length and distant 7.0cm of the source of light.
