An agarose gel was used as the diffusive gel because the classic polyacrylamide gel shows more than 20% of Hg adsorption. According to our results, the Chelex-100 resin presents a much lower affinity for Hg than the thiol based resins. The non-linear accumulation profile of mercury with time for the Chelex-100 resin makes it in fact impossible to use Fick's law for estimating the diffusion coefficient of Hg. The 4 other resins all show a linear accumulation profile of Hg with time. Although the highest accumulation rate is observed for SH-PMO followed by SQR, SH-SBA and SH-KG, these values do not differ very much.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Synthesized mercaptopropyl nanoporous resins in DGT probes for determining dissolved mercury concentrations","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":"    Diffusive Gradients in Thin films;     Labile Hg;     SH-SBA;     SH-PMO;     SQR;     SH-KG","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2015-11-04","DateCreate":"2013-03-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000298452500038","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.talanta.2011.10.012"},"refs":null,"anarec":{"AnaID":223753,"PubliDate":2011,"Pagination":"262-267","XtraPublOfAnaID":null,"ISBN":null,"Volume":"87","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43951,"SerRR":"Talanta.
