The color of ,dye wastewater, depends on its molecular structure. According to the Wiff chromophore theory, one end of the unsaturated conjugated chain (such as -C=C-, -N=N-, -N=O) in the chromophore of the ,dye, molecule contains an electron-donating group (such as -OH ,-NH2) or an electron-absorbing group (such as-NO2, >C=O ), and the other end is connected to the opposite group.

The promoted wet oxidation (PWO) leads to a faster decay of the ,dye, compared with the unpromoted WO experiments. The decomposition of the ,dye, can be described by first-order kinetics over the temperature range. The temperature dependency can be described by an Arrhenius relationship. A reduction in TOC of 70% was achieved at 160 and 190 °C.
