This study investigates the degradation of monochloroacetic acid (MCA) by aluminium modified Fenton Process. Fenton reaction and its modifications using zero-‐valent aluminium (ZVAl) and Al3+ ions have been performed. Influencing factors such as different amounts of hydrogen peroxide, ZVAl and aluminium ions have been studied. Also, the influence of chelating agents (oxalic and citric acids) has been studied. In each system MCA degradation has been achieved and classical Fenton reaction has been improved. Citric acid seems to be a better option to improve the efficiency of the classical Fenton reaction. Environmental toxicity of some resulting solutions with the best efficiencies of degradation has been investigated. From obtained results it is clear, that aluminium modified Fenton reaction is promising method for the degradation of chlorinated pollutants in high concentration.
