Atrazine adsorption was assessed by kinetics and equilibrium assays and desorption was tested with different extraction solvents. Adsorbed atrazine was 100% recovered from sepiolite using 20% acetonitrile solution, while 40% acetonitrile was needed to leach it from cork (98%) and pine bark (94%). Continuous fixed-bed experiments using those sorbents as PRB were performed to evaluate atrazine removal for up-scale applications. The modified dose-response model properly described the breakthrough data. The highest adsorption capacity was achieved by sepiolite (23.3 (\u00b10.8) mg\/g), followed by pine bark (14.8 (\u00b10.6) mg\/g) and cork (13.0 (\u00b10.9) mg\/g). Recyclability of sorbents was evaluated by adsorption-desorption cycles. After two regenerations, sepiolite achieved 81% of atrazine removal, followed by pine with 78% and cork with 54%. Sepiolite had the best performance in terms of adsorption capacity\/stability. SEM and FTIR analyses confirmed no significant differences in material morphology and structure. This study demonstrates that recycling waste\/biowaste is a sustainable option for wastewater treatment, with waste valorization and environmental protection.<\/jats:p>","DOI":"10.3390\/recycling6020041","type":"journal-article","created":{"date-parts":[[2021,6,17]],"date-time":"2021-06-17T21:29:16Z","timestamp":1623965356000},"page":"41","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Cleaner Approach for Atrazine Removal Using Recycling Biowaste\/Waste in Permeable Barriers"],"prefix":"10.3390","volume":"6","author":[{"given":"Ana","family":"Lago","sequence":"first","affiliation":[{"name":"Centre of Biological Engineering, Campus de Gualtar, University of Minho, 4710-057 Braga, Portugal"}]},{"given":"Bruna","family":"Silva","sequence":"additional","affiliation":[{"name":"Centre of Biological Engineering, Campus de Gualtar, University of Minho, 4710-057 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0549-5607","authenticated-orcid":false,"given":"Teresa","family":"Tavares","sequence":"additional","affiliation":[{"name":"Centre of Biological Engineering, Campus de Gualtar, University of Minho, 4710-057 Braga, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"56","DOI":"10.1016\/j.marpolbul.2015.06.038","article-title":"Emerging contaminants (pharmaceuticals, personal care products, a food additive and pesticides) in waters of Sydney estuary, Australia","volume":"97","author":"Birch","year":"2015","journal-title":"Mar.
