Emerging Contaminant degradation of Paracetamol Using Advanced Oxidation Processes

The Emerging contaminants (EC), considered pollutants persistent and refractory it has been the subject studied worldwide. These compounds are present in different environmental matrices in low concentrations and cause damage to the health of animals and humans, which makes alternative treatments may require polishing able to promote its degradation. advanced oxidation processes (AOP) has been applied to this end, so that the present study sought to evaluate the efficiency of two types of AOP (action UV / H(2)O2 and photo-Fenton) in EC paracetamol degradation. In order to quantify and detect with reliability, the compound before and after submission to treatments analysis was performed via LC / MS-IT-TOF with a previously validated method. The results showed that the AOP action UV / H(2)O2 was more efficient achieving promote degradation of paracetamol 100%, which is confirmed by statistical analysis experiments which showed that the addition of free iron (UV / H(2)O2) were the most effective in drug degradation in aqueous solution. Thus, it is possible to verify that the use of bench reactors with UV-C radiation is effective in paracetamol degradation at a low operating cost.
