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. ...
Photochemical processes for removal of carbamate pesticides from water / Fotohemijski procesi za uklanjanje karbamatnih pesticida iz vode
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2019)
A large number of pesticide active ingredients have been registered and marketed for pest control purposes around the world. Most pesticides, including carbamates are resistant to chemical and natural photochemical ...
Properties of cotton yarns after oxidation of potassium permanganate in an acidic environment / Svojstva pamučne pređe posle oksidacije kalijum-permanganatom u kiseloj sredini
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
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 ...
Investigation of copper(i) sulphide leaching in oxidative hydrochloric acid solution
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Present work is focused on the copper (I) sulphide leaching with sodium chloride in hydrochloric acid solution and with introduction of gaseous oxygen. Chemical reactions of leaching and their thermodynamic probabilities ...
Characterization and usefulness of corn cob as biosorbent for Pb2+, Cu2+ and Zn2+ ions removal from aqueous solutions / Karakterizacija i primena oklaska kukuruza za biosorpciju Pb2+, Cu2+ i Zn2+ jona iz vodenog rastvora
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
The objective of this study was to investigate corncob as biosorbent for heavy metals removal from aqueous solutions. All biosorption experiments were performed in batch system. The biosorbent were caracterized by thermal ...
Algorithm for quantifying the particle size distribution of non-metallic inclusions formation in steel production
(Metallurgical & Materials Engineering, 2021)
When the quantitative characterization of non-metallic inclusions in steel is done and the effect of limiting factors is assessed, and based on that the possibility of reconstruction of the total content of non-metallic ...
Applicability of risk-based maintenance strategy to a penstock / Strategija održavanja zasnovana na riziku - primenljivost na cevovod
(Society for Structural Integrity and Life, Institute for Material Testing, 2012)
The risk of brittle fracture of the penstock of the reversible pump turbine is recognized in an early stage of design. To reduce the cost of penstock construction one tunnel is accepted. The HSLA steel of 700 MPa yield ...
Influence of microwave irradiation on hypochlorite decolorisation of synthetic dyes / Uticaj mikrotalasnog zračenja na obezbojavanje sintetskih boja hipohloritom
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
In this study three synthetic dyes were treated using hypochlorite or combination of hypochlorite and microwave irradiation in order to investigate factors which determine decolorisation of the investigated compounds. An ...
