Cu(II) immobilization onto a one-step synthesized poly(4-vinylpyridine-co-ethylene glycol dimethacrylate) resin: Kinetics and XPS analysis
(Savez hemijskih inženjera, Beograd, 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) ...
Carboxymethyl cellulase production from a Paenibacillus sp.
(Savez hemijskih inženjera, Beograd, 2016)
Cellulases are industrially important enzymes with a potential to convert cellulose into fermentable sugars. Novel bacterial isolate Paenibacillus sp. CKS1 was tested for cellulase activity and the optimal conditions for ...
Sepiolite functionalized with N-[3-( trimethoxysilyl)propyl]-ethylenediamine triacetic acid trisodium salt. Part II: Sorption of Ni2+ from aqueous solutions
(Srpsko hemijsko društvo, Beograd, 2016)
The sorption of Ni2+ on sepiolite functionalized by covalent grafting of N-[3-(trimethoxysilyl) propyl] ethylenediamine triacetic acid trisodium salt, MSEAS, was studied in batch experiments as a function of the initial ...
Efficient pollutants removal by amino-modified nanocellulose impregnated with iron oxide
(Srpsko hemijsko društvo, Beograd, 2016)
A novel adsorbent, NC-PEG, obtained by modification of nanocellulose (NC) with PEG-6-arm amino polyethylene glycol (PEG-NH2) via maleic anhydride (MA) linker, was used for removal of Cd2+ and Ni2+ from water. A subsequent ...
Immobilization of maltase from Saccharomyces cerevisiae on thiosulfonate supports
(Srpsko hemijsko društvo, Beograd, 2016)
In this study, two commercial supports (Eupergit (R) C and Purolite (R) A109) were chemically modified in order to introduce thiosulfonate groups, which could subsequently exclusively react with the cysteine residues on ...
A life cycle energy assessment for biogas energy in Serbia
(Taylor & Francis Inc, Philadelphia, 2016)
The aim of this paper was to present the energy flows in the life cycle of biogas utilization systems (cogeneration and transportation), as well as their mutual relations, starting from providing the feedstock for digestion ...
Automatic devices for electrochemical water treatment with cooling of electrolyte
(Savez hemijskih inženjera, Beograd, 2016)
The most common disinfectants for water treatment are based on chlorine and its compounds. Practically, water treatments with chlorine compounds have no alternative, since they provide, in comparison to other effective ...
