The sorption capacities for each metal ion were (in mmol.g-1); Ethanol medium: Cd(II) = 1.45, Cu(II) = 1.85, Ni(II) = 1.65, Pb(II)= 1.40 and Zn(II)= 1.50; Aqueous medium: Cd(II)= 1.30, Cu(II)= 1.80, Ni(II)= 1.50, Pb(II)= 1.20 and Zn(II)= 1.40. A recovery of almost 100% of the metal ions was obtained from ethanol as well as aqueous medium, the ions being sorbed in a column packed with 1 g of Cell-PAB, using 5 mL of 2.0 mol L-1 HCl solution as eluent. An enrichment factor of 45 (250 mL sample, 5 mL concentrate) was obtained by this preconcentration procedure. The sorption desorption procedure applied allowed the development of a preconcentration method for metal ions at trace level in fuel ethanol and natural water samples. After elution, the metal ions were determined by flame atomic absorption spectrometry.","PeriodicalId":375428,"journal":{"name":"Southerns Brazilian journal of chemistry","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115962021","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}
