Electrochemical applications of Fe speciation    measurements vary predominantly in the choice of the added competing    ligand. Although different applications show the same trends, [<em>L</em>]    and log<em>K</em><sup>cond</sup> differ between the applications. In this    study, binding of two added ligands in three different common applications    to three known types of natural binding ligands is compared. The    applications are (1) salicylaldoxime (SA) at 25 µM (SA25) and short waiting    time, (2) SA at 5 µM (SA5), and (3) 2-(2-thiazolylazo)-<em>ρ</em>-cresol    (TAC) at 10 µM, the latter two with overnight equilibration. The three    applications were calibrated under the same conditions, although having    different pH values, resulting in the detection window centers (<em>D</em>)DTAC > DSA25 ≥ SA5 (as log<em>D</em> values with respect to Fe    <sup>3+</sup>: 12.3 > 11.2 ≥ 11).</p><p>For the model ligands, there is no common trend in the results of log    <em>K</em><sup>cond</sup>. The values have a considerable spread, which    indicates that the error in log<em>K</em><sup>cond</sup> is large. The    ligand concentrations of the nonhumic model ligands are overestimated by    SA25, which we attribute to the lack of equilibrium between Fe-SA species    in the SA25 application. The application TAC more often underestimated the    ligand concentrations and the application SA5 over- and underestimated the    ligand concentration. The extent of overestimation and underestimation    differed per model ligand, and the three applications showed the same trend    between the nonhumic model ligands, especially for SA5 and SA25. The    estimated ligand concentrations for the humic and fulvic acids differed    approximately 2-fold between TAC and SA5 and another factor of 2 between    SA5 and SA25.</p><p>The use of SA above 5 µM suffers from the formation of the species Fe(SA)    <em>x</em> (<em>x</em>>1) that is not electro-active as already    suggested by Abualhaija and van den Berg (2014). Moreover, we found that    the reaction between the electro-active and non-electro-active species is    probably irreversible. This undermines the assumption of the CLE principle,    causes overestimation of [<em>L</em>] and could result in a false    distinction into more than one ligand group.</p><p>    For future electrochemical work it is recommended to take the above    limitations of the applications into account. Overall, the uncertainties    arising from the CLE-AdCSV approach mean we need to search for new ways to    determine the organic complexation of Fe in seawater.</p>","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Comparing CLE-AdCSV applications using SA and TAC to determine the Fe-binding characteristics of model ligands in seawater","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-11-30","DateCreate":"2022-11-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000703708400001","VABBcode":null,"OpenAcc":1,"DOI":"10.5194/bg-18-5265-2021"},"refs":null,"anarec":{"AnaID":359561,"PubliDate":2021,"Pagination":"5265-5289","XtraPublOfAnaID":null,"ISBN":null,"Volume":"18","Issue":"19","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":68092,"SerRR":"<b>Gattuso, J.P.; Kesselmeier, J.
