The behaviour of four resins was investigated: DFO-Sepharose, HMP-Sepharose and crosslinked copolymers of 1-(β-acrylamidoethyl)-3-hydroxy-2-methyl-4(1H)-pyridinone (AHMP) with 2-hydroxyethyl methacrylate (HEMA) and of AHMP with N,N-dimethylacrylamide (DMAA). The efficiency of iron detoxification of plasma of the resins was mainly dependent on the affinity of the ligands and the hydrophilicity of the resins. The results of a stability study in phosphate-buffered saline at a physiological pH indicated that AHMP-DMAA was the most stable resin, whereas the Sepharose gels had a relatively lower stability. Experiments with the AHMP-DMAA resin showed that the resin was able to remove iron from plasma with different iron contents, and from plasma poisoned with FeCl<sub>3</sub>, iron(III) citrate or transferrin. A rapid removal from free serum iron was observed, whereas iron from transferrin was removed slowly afterwards. Only the overload iron was removed since in all cases the normal serum iron level of <em>ca</em>. 1 ppm was obtained.</p></div>","PeriodicalId":20864,"journal":{"name":"Reactive Polymers","volume":"23 2","pages":"Pages 63-69"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0923-1137(94)90003-5","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84137025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The modification of this polymer by the substitution of functional groups from organic acids allows new sorbents with high sorption capacities to be obtained: NDTC with ascorbic acid and glutamate glucan with oxo-2-glutaric acid. The mechanism of sorption is investigated and several sorption models are applied such as the Freundlich, Langmuir and Temkin models which fit experimental results well. These results are explained by the heterogeneity of the polymer surface, the variability of metal species in solution and possible interactions between the molecules sorbed. The effects of several parameters such as pH and metal ion concentration are examined and demonstrate the relative importance of metal speciation on sorption performances and mechanisms. The grafting of functional groups creates some heterogeneity of sorption energy, which explains the selectivity seen in the best models. Metal ions are firstly bound onto more energetic sites (nitrogen groups) and later onto other substituting functions.</p></div>","PeriodicalId":20864,"journal":{"name":"Reactive Polymers","volume":"23 2","pages":"Pages 147-156"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0923-1137(94)90015-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91676390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
