Resumen:
Methyl tert-butyl ether (MTBE) is an organic compound toxic and very soluble in water. When MTBE-contaminated water isavailable, it requires some method of decontamination. The Fenton method is used in environmental remediation and watertreatment with low contaminant concentrations. In the search to extend the field of application of this methodology, they werebegun to use catalysts in solid phase, particularly, metallic Fe nanoparticles (ZVI).In our laboratory we have prepared and characterized a supported catalyst (ZVI on a natural zeolite) that was studied for benzenedegradation in experiences in batch and in fixed bed (continuous system) with interesting results. A similar set up was designedfor the experiences described in this paper where aqueous solutions of MTBE with different concentrations were employed. ThepH was regulated at 3.5 with a buffer.Bubble detachment was observed from the catalyst located in the bottom of the erlenmeyer demonstrating an important MTBEmineralization degree. Secondary products of degradation were detected and characterized. For experiences in batch, the MTBEremoval was 45 % approximately in 24 hours. MTBE degradation in columns after the first hour is higher than the observed inthe batch system although it raises a degradation degree in the order of 52% during the entire run.
