| Resumo: | Adsorption is a process that has become indispensable due to pollution caused by
industrial activity. More economically viable adsorbents are being tested to replace the
high cost of materials used. The clays can be used as adsorbents and are low cost
materials, natural properties feasible for the application in the adsorption process,
structural modifications are performed with ease promoting selective adsorption in these
materials. The objective of this study was to synthesize and characterize adsorbents
used in the adsorption of organic compounds. The adsorbents were characterized by the
techniques of XRD, SEM, FTIR and TG. The results show that the studied materials
have affinity to organic compounds and can be applied as adsorbents. The materials
studied are viable and can be applied in the treatment of effluents contaminated in
industrial scale. |
