Contaminants removal from pharmaceutical industry effluents using new materials from waste biodiesel


Due to the increasing environmental pollution, an alternative to minimize it are necessary. The strategy proposed in this paper is the removal of pharmaceutical industry contaminants using carbonaceous materials based on iron/activated carbon obtained from biodiesel residue, thus minimizing the impacts caused by two sources of pollutions. The model contaminant compounds, caffeine, acetaminophen and amoxicillin, and also the actual the pharmaceutical industry effluent will be used. For the removal test the adsorption will take place in batch and a fixed bed column using activated carbons derived from biodiesel residue as adsorbents. Adsorption /oxidation tests of contaminants in the presence of hydrogen peroxide will be carried out using a new material: iron/activated carbon composite, as a catalyst. These composites will be prepared by a new method, in situ, which consists of impregnating a glycerine polymer with iron salt and subsequent activation, thus obtaining an iron/activated carbon composite. For composite preparation, different parameters will be evaluated such as: iron amount and temperature and activation time. After obtaining all composites they will be characterized as to their textural and physicochemical properties by different techniques. The catalytic ability of the composite obtained by the new method will be compared with a composite obtained by the traditional method: incipient wetness impregnation. The best composite obtained will be evaluated in the degradation of real pharmaceutical industry effluent contaminants. The adsorption and oxidation efficiency will be assessed by liquid chromatography (HPLC) and/or UV-vis spectroscopy analyses. Possible oxidation products will be identified by mass spectrometry.
