The presence of these ions promotes phosphate adsorption and the process is electrostatic in nature. Despite this electrostatic force, the precipitation of hydroxyapatite in the presence of Ca<sup>2+</sup> at pH 8.5 also plays an important role in the removal of phosphates from the dissolved phase. Energy dispersive X-ray spectroscopy (EDS) and Fourier transform infrared (FTIR) spectra support that phosphate adsorption on HFO surface can be attributed to inner sphere complexes with the formation of bidentate complexes (FeO)<sub>2</sub>PO<sub>2</sub> in the presence of main seawater ions at pH = 8.5. The results of EDS clearly indicated that Fe-P-Ca complexes, Fe-P-Mg, or other phosphate-bridged ternary complexes were not formed during adsorption in the presence of NaCl, KCl, CaCl<sub>2</sub>, Na<sub>2</sub>SO<sub>4</sub> and MgCl<sub>2</sub>. This observation differs somewhat from that the typical explanation used to describe the phosphate adsorption mechanism on HFO. The CD-MUSIC model makes it possible to describe this adsorption mechanism of phosphate on HFO in the presence of 0.7 M NaCl, and these outcomes are coherent with the experimental FTIR and EDS results.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Influence of seawater ions on phosphate adsorption at the surface of hydrous ferric oxide (HFO)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-23 01:33:10.524411","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Phosphate; HFO; EDS; FTIR; Visual MINTEQ; CD-MUSIC","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2023-02-10","DateCreate":"2021-05-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000535467800007","VABBcode":"vabb:493873","OpenAcc":0,"Handle":"10.1016/j.scitotenv.2020.137826"},"refs":null,"anarec":{"AnaID":337810,"PubliDate":2020,"Pagination":"137826","XtraPublOfAnaID":null,"ISBN":null,"Volume":"721","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43780,"SerRR":"Science of the Total Environment.
