At different pH, the two forms of chromium [Cr(III) and Cr(VI)] have different exchange capacities for 8HQ, therefore two columns were constructed; the pH of column 1 was adjusted to pH\u00a03 for retaining Cr(III) and column 2 was adjusted to pH\u00a01 for retaining of Cr(VI). The sorbed Cr(III) and Cr(VI) species were eluted from columns using 3.0\u00a0ml of 0.1\u00a0N of HCl and 3.0\u00a0ml of 0.1\u00a0N of NaOH, respectively. The flow injection\u2013chemiluminescence (FI\u2013CL) method is based on light emitted due to the oxidation of DEAPH by the H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    in the presence of Cr(III), which catalyzes the reaction. The flow cell is a transparent coiled tube made from glass (2.0\u00a0\u00d7\u00a04.0, inner and outer diameter) and located close to the photodetector. The flow parameters: flow rate, sample volume, flow cell length, and distance to the CL detector were studied and optimized. Under optimum flow conditions, the Cr(III) concentration can be determined over the range 5\u2013350\u2009\u03bcg\u2009L\n                    <jats:sup>\u22121<\/jats:sup>\n                    with a limit of detection of 1.2\u00a0\u03bcg\u2009L\n                    <jats:sup>\u22121<\/jats:sup>\n                    , as the Cr(III) concentration is proportional to the intensity of the CL signal. The relative standard deviations (%) for 10 and 50\u2009\u03bcg\u2009L\n                    <jats:sup>\u22121<\/jats:sup>\n                    Cr(III) were 1.2% and 3.2%, respectively. The effects of Al(III), Cd(II), Zn(II), Hg(II), Pb(II), Co(II), Cu(II), Ni(II), Mn(II), Ca(II), and Fe(III) were investigated. The proposed method is highly selective and sensitive, enabling a rapid determination of the Cr(III) amount in the presence of other interfering metals. Finally, the FI\u2013CL method was examined in five river water samples with excellent recoveries.\n                  <\/jats:p>","DOI":"10.1002\/bio.4464","type":"journal-article","created":{"date-parts":[[2023,2,13]],"date-time":"2023-02-13T03:05:11Z","timestamp":1676257511000},"page":"360-368","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Online column preconcentration for speciation and selective determination of Cr(III) in natural water samples using flow injection with chemiluminescence detection"],"prefix":"10.1002","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3286-8173","authenticated-orcid":false,"given":"Aktham N.","family":"Jasim","sequence":"first","affiliation":[{"name":"College of Basic Education, Science Department Al \u2013 Mustansiryah University  Baghdad Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Azhar","family":"Kamel","sequence":"additional","affiliation":[{"name":"College of Pharmacy Al\u2010Bayan University  Baghdad Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nagham S.","family":"Al\u2010Awadi","sequence":"additional","affiliation":[{"name":"Department of Chemistry<sup>,<\/sup> College of Science University of Baghdad  Baghdad Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hussein Fares","family":"Abd\u2010Alrazack","sequence":"additional","affiliation":[{"name":"National Oil Company, Iraq Drilling Company  Baghdad Iraq"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,2,18]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/03067318708075445"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0048-9697(89)90189-7"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbrc.2008.02.083"},{"key":"e_1_2_7_5_1","volume-title":"Environmental engineering: Environmental health and safety for municipal infrastructure, land use and planning, and industry","author":"Nemerow N.
