Sažetak
Cilj ovog rada je proučavanje uticaja neselektivne oksidacije celuloze (pamučna pređa) kalijumpermanganatom u kiseloj sredini, na promenu sorpcionih svojstava (joni srebra) i sadržaj deponovanog mangan(IV)-oksida. Tokom eksperimenta korišćene su standardne metode i metode razvijene na Katedri za tekstilno inženjerstvo Tehnološko-metalurškog fakulteta u Beogradu. Za određivanje sadržaja mangan(IV) oksida deponovanog na pamučnoj pređi je korišćena optička emisiona spektrometrija sa induktivno spregnutom plazmom (ICP-OES). Promene ispitivanih svojstava pamučnih pređa su ispraćene u funkciji koncentracije i pH rastvora oksidacionog sredstva. Rezulati dobijeni u ovom radu su pokazali da je oksidovana pamučna pređa pogodna polazna sirovina za dobijanje širokog spektra tekstilnih proizvoda specijalne namene.

Abstract
The impact of nonselective cellulose oxidation (cotton fibre) by potassium permanganate in acidic environment, with or without additional treatment by sodium metabisulfite, on change of sorption (silver ions sorption), and deposition of manganese (IV) oxide were aims of this work. The standard methods and methods developed at Department of Textile Engineering of Faculty of Technology and Metallurgy Belgrade, were used for determination of introduced functional groups, sorption and mechanical properties of selected fibres. Inductively coupled plasma optical emission spectrometry ICP-OES was used for determination of manganese(IV) oxide deposited on cotton fibres. The changes of studied properties of cotton fibres were followed as a function of concentration and pH of the solution of oxidizing agent. Results obtained in this work showed that oxidized cotton fibre with improved sorption properties is appropriate as an initial raw for a wide range of textile products of special assignment.
