Removal of aqueous Cu 2+ ions with Fe 0 /C ceramsites fabricated by direct reduction roasting of magnetite, coal, and paper mill sludge
The porous metallic iron/carbon (Fe /C) ceramsites, with virtues of low cost and 'green' fabrication, were prepared by direct reduction roasting of magnetite, coal, and paper mill sludge. The X-ray diffraction data revealed that Fe was generated in situ by reducing the magnetite at 1,200 °...

particles, with a size of <10 μm, were highly dispersed on carbon particles to form an integrated anode (Fe
) and cathode (C) structure of microelectrolysis filters. The effects of initial solution pH and Fe/C mass ratio on Cu
removal were investigated. The extent of Cu
removal increased from 93.53% to 99.81% as initial pH rose from 2.5 to 7.0. The residual Cu
concentration was as low as <0.2 mg/L. The highest extent of Cu
removal was achieved at Fe/C mass ratio of 6.8:1. The pseudo-second-order kinetic model fitted well for Cu
removal by the ceramsite, revealing the chemisorption as a limiting step. The Cu
adsorption equilibrium data were well described by the Langmuir isotherm, with a maximum adsorption capacity of 546.45 mg/g at initial pH 3.0.</description><identifier>ISSN: 0273-1223</identifier><identifier>DOI: 10.2166/wst.2018.457</identifier><identifier>PMID: 30500799</identifier><language>eng</language><publisher>England</publisher><subject>Adsorption ; Coal ; Copper - analysis ; Copper - chemistry ; Ferrosoferric Oxide - analysis ; Ferrosoferric Oxide - chemistry ; Hydrogen-Ion Concentration ; Ions ; Kinetics ; Sewage ; Waste Disposal, Fluid - methods ; Water Pollutants, Chemical - analysis ; Water Pollutants, Chemical - chemistry</subject><ispartof>Water science and technology, 2018-11, Vol.78 (8), p.1753</ispartof><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27901,27902</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/30500799$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Fu, Pingfeng</creatorcontrib><creatorcontrib>Chen, Zihao</creatorcontrib><creatorcontrib>Yang, Tianwen</creatorcontrib><title>Removal of aqueous Cu 2+ ions with Fe 0 /C ceramsites fabricated by direct reduction roasting of magnetite, coal, and paper mill sludge</title><title>Water science and technology</title><addtitle>Water Sci Technol</addtitle><description>The porous metallic iron/carbon (Fe
