Organic pollutants are an outstanding problem due to their high toxicity and difficulty in removing them, among the dyes assiduously dumped by the textile industry stand out, being methylene blue one of the most frequent. For its removal, a variety of techniques have been studied, where adsorption process is one of the most used. A wide variety of adsorbents have been experienced, where those from natural materials have shown great efficiency, in addition to being low cost. The problem arises when using these adsorbents in powder form since it generates difficulties in its handling and extraction from the medium. In this work we propose the use of adsorbent materials arranged in a ceramic matrix like monoliths with honey comb structure, synthesized from zeolites and natural clays. These materials were studied in the removal of methylene blue finding an average value of removal capacity of 10 mg MB per gram of adsorbent.
