Abstract: This study describes a new method to perform the kinetic study of toxic pollutants decomposition by ozone in landfill leachate using a novel numerical adaptive method based on the classical least square method. The leachate was obtained from the Mexico City waste sanitary landfill (Bordo Poniente) and was treated by ozonation after a coagulation treatment with Fe₂(SO₄)₃. For the partial identification of the initial organic matter composition, intermediates and final products of ozonation, the extraction of the initial and ozonated leachate with benzene, chloroform : methanol (2 : 1) and hexane was carried out, and then the extracts were analysed with a gas chromatography.
