Efficacy of Different Waste and By-Products from Forest and Food Industries in the Removal/Retention of the Antibiotic Cefuroxime

Environmental pollution due to antibiotics is a serious problem. In this work, the adsorption and desorption of antibiotic cefuroxime (CFX) were studied in four by-products/residues from forestry food industries. For this, batch-type experiments carried out, adding increasing concentrations CFX (from 0 50 µmol L?1) 0.5 g adsorbent. The materials with pH higher than 9 (mussel shell wood ash) those that presented highest percentages, 71.2% (23.1 kg?1) 98.6% (928.0 kg?1). rest adsorbents, was also around 100% when lowest added, but percentage dropped sharply dose incorporated. Adsorption data fitted well Langmuir Freundlich models, R2 greater 0.9. Regarding desorption, values concentration added ash (0%) mussel (2.1%), while pine bark eucalyptus leaves (26.6% 28.6%, respectively). Therefore, could be considered adsorbents high potential used problems environmental contamination by CFX.
