The Fe3O4@CSH material was characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), powder Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), zeta-potential and magnetic curves. The chemical composition and structure of Fe3O4@CSH and the successful surface loading of hydroxyl functional groups were confirmed. Phosphate adsorption kinetics, isotherm, and thermodynamic experiments showed that adsorption reaches equilibrium at 24 h, with a maximum adsorption capacity of 55.84 mg P\/g under optimized experimental conditions. Adsorption kinetics fitted well to the pseudo second-order model, and equilibrium data fit the Freundlich isotherm model. Thermodynamic analysis provided a positive value for \u0394H\u00b0 (129.84 KJ\/mol) and confirmed that phosphate adsorption on these materials is endothermic. The P-laden Fe3O4@CSH materials could be rapidly separated from aqueous solution by a magnetic separation technique within 1 min. A removal rate of more than 60% was still obtained after eight adsorption\/desorption cycles, demonstrating the excellent reusability of the particles. The results demonstrated that the Fe3O4@CSH materials had high P-adsorption efficiency and were reusable.<\/jats:p>","DOI":"10.2166\/wst.2018.184","type":"journal-article","created":{"date-parts":[[2018,4,18]],"date-time":"2018-04-18T11:45:57Z","timestamp":1524051957000},"page":"578-591","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":21,"title":["Performance and adsorption mechanism of a magnetic calcium silicate hydrate composite for phosphate removal and recovery"],"prefix":"10.2166","volume":"2017","author":[{"given":"Lihong","family":"Peng","sequence":"first","affiliation":[{"name":"School of Energy and Environment, Southeast University, No. 2 Sipailou Road, Nanjing 210096, China"},{"name":"ERC Taihu Lake Water Environment (Wuxi), No. 99 Linghu Road, Wuxi 214135, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongliang","family":"Dai","sequence":"first","affiliation":[{"name":"School of Energy and Environment, Southeast University, No. 2 Sipailou Road, Nanjing 210096, China"},{"name":"ERC Taihu Lake Water Environment (Wuxi), No. 99 Linghu Road, Wuxi 214135, China"},{"name":"School of Environmental and Chemical Engineering, Jiangsu University of Science and Technology, Zhenjiang 212018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifeng","family":"Wu","sequence":"first","affiliation":[{"name":"School of Energy and Environment, Southeast University, No. 2 Sipailou Road, Nanjing 210096, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zheqin","family":"Dai","sequence":"first","affiliation":[{"name":"School of Energy and Environment, Southeast University, No. 2 Sipailou Road, Nanjing 210096, China"},{"name":"ERC Taihu Lake Water Environment (Wuxi), No. 99 Linghu Road, Wuxi 214135, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang","family":"Li","sequence":"first","affiliation":[{"name":"School of Energy and Environment, Southeast University, No. 2 Sipailou Road, Nanjing 210096, China"},{"name":"ERC Taihu Lake Water Environment (Wuxi), No. 99 Linghu Road, Wuxi 214135, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiwu","family":"Lu","sequence":"first","affiliation":[{"name":"School of Energy and Environment, Southeast University, No. 2 Sipailou Road, Nanjing 210096, China"},{"name":"ERC Taihu Lake Water Environment (Wuxi), No. 99 Linghu Road, Wuxi 214135, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","published-online":{"date-parts":[[2018,4,18]]},"reference":[{"issue":"4","key":"2020032811204686200_WST-EM171390C1","doi-asserted-by":"crossref","first-page":"375","DOI":"10.3390\/ijerph13040375","article-title":"Concurrent phosphorus recovery and energy generation in mediator-less dual chamber microbial fuel cells: mechanisms and influencing factors","volume":"13","year":"2016","journal-title":"Int.
