Effects of operating parameters on efficiency of lead removal by complexation-microfiltration process / Uticaj radnih parametara na efikasnost uklanjanja jona olova pomoću kompleksirajuće-mikrofiltracionog procesa
(Association of Chemical Engineers of Serbia, 2012)
The majority of lead content found in the environment is a result of human activities. Heavy metals can be hazardous because they tend to bioaccumulate. A complexation-microfiltration process for the removal of Pb(II) ions ...
Roughness measurement as an alternative method in evaluation of cavitation resistance of steel / Merenje hrapavosti kao alternativna metoda u proceni kavitacione otpornosti čelika
(Association of Chemical Engineers of Serbia, 2013)
The purpose of this study was to investigate possible application of roughness measurement in the evaluation of resistance of steel under conditions of cavitation effect, where these materials are commonly used. Different ...
Effect of tungsten carbide in carbon Pt catalyst support on electrochemical oxygen reduction in acid solution / Uticaj prisustva volfram-karbida u ugljeničnom nosaču Pt nanočestica na elektrohemijsku redukciju kiseonika u kiselom rastvoru
(Association of Chemical Engineers of Serbia, 2013)
Tungsten carbide was synthesized by calcination of carbon cryogel with embedded tungsten in a form of metatungstate. This material was used as a support for Pt nanoparticles. XRD pattern of W-C support indicated the presence ...
