Immobilization of enzymes onto carbon nanotubes / Imobilizacija enzima na ugljenične nanocevi
(Association of Chemical Engineers of Serbia, 2011)
The discovery of carbon nanotubes (CNTs) has opened a new door in nanotechnology. With their high surface area, unique electronic, thermal and mechanical properties, CNTs have been widely used as carriers for protein ...
Arsenic removal from water using low-cost adsorbents - a comparative study / Pregled savremenih metoda za uklanjanje arsena iz vode
(Serbian Chemical Society, Belgrade, 2011)
Inorganic arsenic removal from water using low-cost adsorbents is presented in this paper. Selective removal of As(III) and As(V) from water was performed with natural materials (zeolite, bentonite, sepiolite, pyrolusite ...
Adsorption study of cadmium ions on kaolinite modified by histidine and cysteine / Adsorpcija kadmijumovih jona na kaolinitu modifikovanim histidinom i cisteinom
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Continuous development of new technologies leads to increasing pollution of water, thus creating the need for new materials that could be used in the processes of its purification. Therefore, adsorbents prepared from ...
Application of alumosilicate polymers based on metakaolin in adsorption of cadmium ions from wastewater / Primena alumosilikatnih polimera na bazi metakaolina u adsorpciji jona kadmijuma iz otpadnih voda
(Savez inženjera i tehničara Srbije, Beograd, 2018)
Alumosilicate polymers (geopolymers) based on metakaolin as precursor and alkaline activators of different concentrations (2M, 4M, 6M and 8M NaOH/Na2SiO3) were used to remove ions of cadmium from wastewater. Experiments ...
Application of raw volcanic rock found in etna valley as an adsorbent of chromates, arsenates and selenates
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This paper aims to determine the potential of volcanic rock found in Etna valley as an adsorbent of heavy metals in anionic form (chromates, arsenates, and selenates). Characterization of the volcanic rock was done with ...
Prirodni adsorbenti na bazi metalnih oksida za uklanjanje jona olova i arsena iz vodenih rastvora
(Departman za energetiku i procesnu tehniku - FTN, 2021)
U ovom radu ispitana su adsorpciona svojstva tri prirodna mineralna materijala za uklanjanje
Pb(II) i As(V) jona iz vodenih rastvora. Sveobuhvatna strukturna analiza pokazala je glavne mineralne komponente, SiO2, Al2O3 i ...
The Application of a Natural Zeolite for Acid Mine Drainage Purification
(Japan Inst Metals & Materials, Sendai, 2015)
A natural zeolite from Serbia was employed for the removal of heavy metals from acid mine drainage (AMD) generated in the area of copper mine. The efficiency of the natural zeolite samples was tested on AMD that contained ...
Bisphenol a removal from aqueous solution using fine alpha-fe2o3 particles
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Iron(III) oxide particles (alpha-Fe2O3) were obtained from ferrous chloride (FeCl3 center dot 6H(2)O) precursor using ammonium hydroxide as a precipitating agent and particles were calcined at 700 degrees C for 4 h. ...
ORGANIC DYES ADSORPTION ON CARBON ADSORBENTS DERIVED FROM WASTE COTTON AND COTTON/POLYESTER YARN / ADSORPCIJA ORGANSKIH BOJA NA UGLJENIČNIM ADSORBENTIMA DOBIJENIM OD OTPADNOG PREDIVA PAMUKA I PAMUK/POLIESTRA
(Belgrade : Union of Engineers and Textile Technicians of Serbia, 2023)
In an attempt to reuse fibrous textile waste, and at the same time to reduce its quantity, waste cotton-based yarn was used as a cheap and sustainable precursor for carbon adsorbents production. Cotton and cotton/polyester ...
Ispitivanje adsorpcionih svojstava ilovače za uklanjanje jona olova i arsena iz vodenih rastvora
(Akademija tehničkih strukovnih studija Beograd, 2021)
Olovo i arsen predstavljaju značajnu grupu neorganskih polutanata koji su prisutni u
životnoj sredini, pre svega u vodenim sistemima, pa je njihovo uklanjanje veliki tehničkotehnološki izazov. Zbog toga se sve više pažnje ...
