Batch adsorption experiments were conducted to investigate the adsorption kinetics and isotherm. Application of continuous phosphate removal was achieved via lab-scale column reactors. The phosphate adsorption equilibrium data of the La-SBC-CS fitted well with the Freundlich isotherm, with a maximum adsorption amount of 81.54 mg p\/g at 25 \u00b0C. Characterization of the adsorbent using scanning electron microscopy analysis (SEM), X-ray energy spectrum analysis (EDS), X-ray diffraction analysis (XRD) and Fourier infrared analysis (FTIR) techniques suggested that the possible adsorption mechanisms were electrostatic interaction, ligand exchange and complexation. The La-SBC-CS kept 76.37% phosphate removal efficiency after eight recycles. The results of continuous column reactor experiment demonstrated that the breakthrough time increased with an increase in adsorbent filling height, while it decreased with an increase in initial phosphate concentration or flow velocity. The Yoon model was applied to the continuous experimental data to predict breakthrough curves and determined the characteristic adsorption parameters for process design. This study indicated the potential for the practical application of La-SBC-CS in phosphate removal from wastewater.<\/jats:p>","DOI":"10.2166\/wst.2021.485","type":"journal-article","created":{"date-parts":[[2021,11,9]],"date-time":"2021-11-09T18:34:58Z","timestamp":1636482898000},"page":"3891-3906","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":23,"title":["Removal of phosphate from aqueous solution by chitosan coated and lanthanum loaded biochar derived from urban dewatered sewage sludge: adsorption mechanism and application to lab-scale columns"],"prefix":"10.2166","volume":"84","author":[{"given":"Xiaoling","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Water and Environment, Chang'an University, Xi'an 710064, China"},{"name":"Key Laboratory of Subsurface Hydrology and Ecological Effects in Arid Region of the Ministry of Education, Chang'an University, Xi'an 710064, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xincong","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Water and Environment, Chang'an University, Xi'an 710064, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2944-1526","authenticated-orcid":false,"given":"Zhuo","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Water and Environment, Chang'an University, Xi'an 710064, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziwei","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Water and Environment, Chang'an University, Xi'an 710064, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2021,11,9]]},"reference":[{"key":"key-10.2166\/wst.2021.485-1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jwpe.2020.101323"},{"key":"key-10.2166\/wst.2021.485-2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cej.2020.128211"},{"key":"key-10.2166\/wst.2021.485-3","doi-asserted-by":"publisher","DOI":"10.1007\/s11051-012-0900-y"},{"key":"key-10.2166\/wst.2021.485-4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhazmat.2020.123130"},{"key":"key-10.2166\/wst.2021.485-5","doi-asserted-by":"publisher","DOI":"10.1016\/j.seppur.2019.116285"},{"key":"key-10.2166\/wst.2021.485-6","doi-asserted-by":"publisher","DOI":"10.1016\/j.biortech.2016.07.072"},{"key":"key-10.2166\/wst.2021.485-7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclepro.2018.10.027"},{"key":"key-10.2166\/wst.2021.485-8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jenvman.2013.09.045"},{"key":"key-10.2166\/wst.2021.485-9","doi-asserted-by":"publisher","DOI":"10.1016\/j.reactfunctpolym.2019.104372"},{"key":"key-10.2166\/wst.2021.485-10","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2021.149888"},{"key":"key-10.2166\/wst.2021.485-11","doi-asserted-by":"publisher","DOI":"10.1016\/j.jes.2014.08.019"},{"key":"key-10.2166\/wst.2021.485-12","doi-asserted-by":"publisher","DOI":"10.1016\/j.clay.2017.11.032"},{"key":"key-10.2166\/wst.2021.485-13","doi-asserted-by":"publisher","DOI":"10.1016\/j.colsurfa.2018.09.016"},{"key":"key-10.2166\/wst.2021.485-14","doi-asserted-by":"publisher","DOI":"10.1016\/j.molliq.2019.111815"},{"key":"key-10.2166\/wst.2021.485-15","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcis.2017.11.003"},{"key":"key-10.2166\/wst.2021.485-16","first-page":"100272","article-title":"In-situ fabrication of cerium incorporated chitosan-\u03b2-cyclodextrin microspheres as an effective adsorbent for toxic anions removal","volume":"12","author":"Karthikeyan","year":"2019","journal-title":"Environ.
