![]() The resultant concentrated elements were determined by flame atomic absorption spectrometric determinations. The method, thus, has been called carrier element-free coprecipitation ( CEFC). Basri Elci, LatifĪ separation/preconcentration procedure, based on the coprecipitation of Cr 3+, Fe 3+, Pb 2+ and Zn 2+ ions using a new organic coprecipitant, 3-phenly-4-o-hydroxybenzylidenamino-4,5-dihydro-1,2,4-triazole-5-one (POHBAT) without adding any carrier element has been developed. ![]() Gundogdu, Ali Ozdes, Duygu Yildirim, Nuri Soylak, Mustafa Senturk, H. International Nuclear Information System (INIS)ĭuran, Celal Bulut, Volkan N. The proposed method was successfully applied to environmental samples for the determination of the analytes.Ĭarrier element-free coprecipitation with 3-phenly-4-o-hydroxybenzylidenamino-4,5-dihydro-1,2,4-triazole-5-one for separation/preconcentration of Cr(III), Fe(III), Pb(II) and Zn(II) from aqueous solutions The precision of the method evaluated as relative standard deviation (R.S.D.), was in the range of 3-7% depend on the analytes. After reduction of chromium(VI) by concentrated H. In this method a newly synthesized organic coprecipitant, 5-chloro-3-indolin-2-one (CFMEPI), was used without adding any carrier element for coprecipitation of chromium(III). The present speciation procedure for Cr(III) and Cr(VI) is based on combination of carrier element-free coprecipitation ( CEFC) and flame atomic absorption spectrometric (FAAS) determinations. Carrier element-free coprecipitation ( CEFC) method for the separation, preconcentration and speciation of chromium using an isatin derivativeĮnergy Technology Data Exchange (ETDEWEB)īulut, Volkan Numan Ozdes, Duygu Bekircan, Olcay Gundogdu, Ali Duran, Celal, E-mail: new, simple, rapid and sensitive separation, preconcentration and speciation procedure for chromium in environmental liquid and solid samples has been established.
