Glycidyl methacrylate macroporous copolymer grafted with diethylene triamine as sorbent for Reactive Black 5
(Hemijska industrija, 2014)
In this paper, macroporous glycidyl methacrylate and ethylene glycol dimethacrylate copolymer functionalized with diethylene triamine (PGME-deta), was evaluated as Reactive Black 5 (RB5) sorbent. Batch RB5 removal from ...
Cracking caused by cutting of plasma-sprayed hydroxyapatite coatings and its relation to the structural features of coatings deposited at different initial substrate temperatures
(Hemijska industrija, 2017)
The present study estimated the cracking phenomenon in as-plasma-sprayed hydroxylapatite coatings (HACs) after they were being subjected to the severe cutting conditions in the direction perpendicular to the coating/substrate ...
Removal of Pb2+ from aqueous solution by P(HEA/IA) hydrogels
(Hemijska industrija, 2016)
A series of poly(2-hydroxyethyl acrylate-co-itaconic acid), P(HEA/IA), hydrogels with different HEA/IA ratio, were synthesized using free radical crosslinking/copolymerization and investigated as sorbents for Pb2+ from ...
Mass Spectrometric Production of Heterogeneous Metal Clusters Using Knudsen Cell
(Hemijska industrija, 2016)
Knudsen effusion mass spectrometry or high-temperature method of mass spectrometry for decades gives new information about saturated vapor of hardly volatile compounds and it is an important method in the discovery of many ...
Influence of Organic Cations Sorption on the Point of Zero Charge of Natural Zeolite
(Hemijska industrija, 2009)
In this paper, the results of the surface modification of natural zeolite with different amounts (2, 5 and 10 mmol M(+)/100 g) of octadecyldimethylbenzyl ammonium ions (ODMBA) are presented. The obtained organozeohtes were ...
Experimental and numerical study of globe valve housing
(Hemijska industrija, 2017)
Complex structure experimental analysis has always been a huge challenge for researchers. Conventional experimental methods (e.g., strain gauges) give only limited data sets regarding measurement on critical areas with ...
Decolorization of crystal violet over TiO2 and TiO2 doped with zirconia photocatalysts
(Hemijska industrija, 2017)
Titania based catalyst and TiO2 doped with zirconia were prepared by modified sol-gel method. The synthesized catalysts samples were characterized by BET, XRD, SEM and FTIR techniques. Photocatalytic activity was tested ...
Economizer water-wall damages initiated by feedwater impurities
(Hemijska industrija, 2014)
The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of ...
Granular flow in static mixers by coupled DEM/CFD approach
(Hemijska industrija, 2016)
The mixing process greatly influences the mixing efficiency, as well as the quality and the price of the intermediate and/or the final product. Static mixer is used for premixing action before the main mixing process, for ...
Cu(II) immobilization onto a one-step synthesized poly(4-vinylpyridine-co-ethylene glycol dimethacrylate) resin: Kinetics and XPS analysis
(Hemijska industrija, 2016)
Synthesis of an unconventional resin based on 4-vinylpyridine (4-VP) and its Cu(II) sorption behavior were studied. Three samples of macroporous crosslinked poly(4-vinylpyridine-co-ethylene glycol dimethacrylate) (P4VPE) ...
