Modeling of disperse dye adsorption on modified polyester fibers
(University of Novi Sad, Faculty of Technology, 2020)
The results of the research on the ability of adsorption of dye on polyester fibers at a temperature of 98 °C are presented in this paper. The fibers were previously modified in aqueous solutions of NaOH, KOH or Al(OH)3. ...
Solvatochromism of 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones / Solvatohromizam 5-(4-supstituisanih arilazo)-4-fenil-6-metil-3-cijano-2-piridona
(Engineering Society for Corrosion, Belgrade, Serbia, 2018)
Eight 5-(4-substituted arylazo)-4-phenyl-6-methyl-3-cyano-2-pyridones were synthesized by reaction of benzoylacetone and arendiazonium salt, followed by condensation with cyanoacetamide. Absorption spectra of all azo ...
Integrated procedure for recycling and valorization of useful components from secondary raw materials based on hard metals
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Wide application of hard metals requires increased consumption of their constituents. Their high cost and scarcity impose the need for finding new, both ecologically and economically justified ways for their production. ...
