Titre : A reliable detection method for Cr(VI) in dyed leathers by Ion chromatography Type de document : texte imprimé Auteurs : Rama Jeevan Ganesh Jeevan, Auteur ; Ganga Radhakrishnan, Auteur ; Raghavan Chandrasekar, Auteur Année de publication : 2003 Article en page(s) : p. 344-350 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Cr(VI) detection without false positives in coloured (dyed) leather is an important issue. Several studies have highlighted the problems faced and the unreliability of the present official procedures viz. IUC-18, DIN 53314 and EN 420 especially when applied to coloured leathers. This is due to colourants soluble in the extractant interfering seriously when analysed by visible spectrophotometry. In the present study a method has been developed which targets cleaning of the matrix elements mainly dye in the first step, followed by ion chromatography with post column derivatization using DPC (1,5-diphenylcarbazide). The method is found to work with greater reliability, as ascertained from several Cr(VI) spiked studies on deliberated matrix preparations constituting Cr(III) and dyes. The study included analyses of several coloured leathers, and their spiked leather extracts and comparison of official procedures with IC (Ion chromatography) involving wet blue and light coloured leathers.

Titre : A simple and effective method for Cr(VI) analysis in dyed leathers Type de document : texte imprimé Auteurs : R. Ganeshjeevan, Auteur ; Raghavan Chandrasekar, Auteur ; S. Shanmuga Priya, Auteur ; Ganga Radhakrishnan, Auteur Année de publication : 2004 Article en page(s) : p. 12-15 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Spectrophotometric detection of Cr(VI) by 1,5-diphenylcarbazide derivatization method recommended by the IUC-18 protocol suffers seriously due to the interference of colorants present in dyed leather extracts. Recently a C-18 reverse phase cartridge clean up for the color removal was recommended but the method has limitations. The present paper suggests an alternate material, which serves better for the removal of interfering colors. This method is rapid, very effective, and economic for the detection of Cr(VI) in finished leathers.
