The activated carbon was tested by SEM, EDX, BET, XRD, FTIR, and XPS. This activated carbon exhibited a high BET surface area of 831 m2 g\u22121 with the average pore diameter and pore volume reaching 2.52 nm and 0.45 m3 g\u22121, respectively. The batch experimental results can be described by Freundlich equation, pseudo-second-order kinetics, and the intraparticle diffusion model, while the maximum adsorption capacity reached 239.6 mg g\u22121 under 318 K. The effects of flow rate, bed height, initial concentration, and temperature were studied in fixed bed adsorption experiments, and adsorption data were fitted with six dynamic adsorption models. The results of characterizations and the batch experiments were analyzed to study the adsorption and desorption mechanisms. Tetracycline hydrochloride and activated carbon were bonded together by \u03c0\u2013\u03c0 interactions and cation\u2013\u03c0 bonds. Ethanol was used as an eluent which bonded with 10 hydrogen bond acceptors on tetracycline hydrochloride to form a complex by hydrogen bonding to achieve recycling.<\/jats:p>","DOI":"10.3390\/molecules24244534","type":"journal-article","created":{"date-parts":[[2019,12,12]],"date-time":"2019-12-12T03:20:16Z","timestamp":1576120816000},"page":"4534","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":75,"title":["Adsorption and Desorption Performance and Mechanism of Tetracycline Hydrochloride by Activated Carbon-Based Adsorbents Derived from Sugar Cane Bagasse Activated with ZnCl2"],"prefix":"10.3390","volume":"24","author":[{"given":"Yixin","family":"Cai","sequence":"first","affiliation":[{"name":"Beijing Advanced Innovation Center for Food Nutrition and Human Health, Beijing Technology &amp; Business University (BTBU), Beijing 100048, China"},{"name":"School of Chemical Engineering and Pharmacy, Wuhan Institute of Technology, LiuFang Campus, No.206, Guanggu 1st road, Donghu New &amp; High Technology Development Zone, Wuhan 430205, Hubei Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liming","family":"Liu","sequence":"additional","affiliation":[{"name":"Beijing Advanced Innovation Center for Food Nutrition and Human Health, Beijing Technology &amp; Business University (BTBU), Beijing 100048, China"},{"name":"School of Chemical Engineering and Pharmacy, Wuhan Institute of Technology, LiuFang Campus, No.206, Guanggu 1st road, Donghu New &amp; High Technology Development Zone, Wuhan 430205, Hubei Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huafeng","family":"Tian","sequence":"additional","affiliation":[{"name":"Beijing Advanced Innovation Center for Food Nutrition and Human Health, Beijing Technology &amp; Business University (BTBU), Beijing 100048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhennai","family":"Yang","sequence":"additional","affiliation":[{"name":"Beijing Advanced Innovation Center for Food Nutrition and Human Health, Beijing Technology &amp; Business University (BTBU), Beijing 100048, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaogang","family":"Luo","sequence":"additional","affiliation":[{"name":"Beijing Advanced Innovation Center for Food Nutrition and Human Health, Beijing Technology &amp; Business University (BTBU), Beijing 100048, China"},{"name":"School of Chemical Engineering and Pharmacy, Wuhan Institute of Technology, LiuFang Campus, No.206, Guanggu 1st road, Donghu New &amp; High Technology Development Zone, Wuhan 430205, Hubei Province, China"},{"name":"School of Materials Science and Engineering, Zhengzhou University, No.100 Science Avenue, Zhengzhou 450001, Henan Province, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"88","DOI":"10.1016\/j.cej.2012.09.072","article-title":"Kinetic study of tetracycline adsorption on sludge-derived adsorbents in aqueous phase","volume":"213","year":"2012","journal-title":"Chem.
