| Abstract |
The use of forest by-products as bio-adsorbents allows the recycling of these materials and could reduce the risks of environmental pollution due to different contaminants. This study focuses on the adsorption and release of three antibiotics (ciprofloxacin, clarithromycin and trimethoprim) on pine and oak bark materials and how pH influences in these processes. The results showed that the highest adsorption potential corresponds to pine bark, where the Freundlich affinity coefficient varies between 126.6 and 2979.1 Ln mu mol1-n kg-1, while, for oak bark, between 283.9 and 806.9 Ln mu mol1-n kg-1. Both bio-adsorbents show some influence of the pH affecting adsorption. Of the three antibiotics, clarithromycin was the most mobile. In general, both by-products gave satisfactory results as bio-adsorbents for the antibiotics tested. Therefore, their potential use as decontaminants could help to face environmental issues due to these emerging pollutants, reducing human and ecological risk, while contributing to a zero-waste economy. |
