As a result, an amphoteric chelating resin with guanidyl and carboxyl groups at a concentration of <em>ca</em>. 13and 2–4 mmol/g, respectively, is obtained. The resin possesses a porous structure with a mean pore radius of 5.6 nm in swollen state. The sorption of Cu(II) ions increases with increasing content of functional groups, and reaches 120–170 mg/g at pH 5. The equilibrium sorption is attained after 300 min. The infrared (IR) spectra of resins confirm that both guanidyl and carboxyl groups form complexes with Cu(II) ions. From analysis of the sorption degree of Cu(II) ions it can be concluded that statistically two groups (carboxyl or/and guanidyl) participate in the complexation. Electron paramagnetic resonance (EPR) spectra of the resins suggest that at low pH the complexes of Cu(II) ions with carboxyl groups dominate. At the pH range 3–8 the formation of Cu(II) complexes with carboxyl and guanidyl groups is evident. At pH > 9 three or four nitrogen atoms participate in coordination sphere around Cu(II).</p></div>","PeriodicalId":20864,"journal":{"name":"Reactive Polymers","volume":null,"pages":null},"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)90002-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73578454","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 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":null,"pages":null},"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}
