Synthesis and swelling behavior of polyurethane networks based on hyperbranched polymer
(Hemijska industrija, 2011)
A series of six polyurethane (PU) networks was synthesized from Boltorn (R) hydroxy-functional hyperbranched polyester (HBP) of the second pseudo generation as a cross-linking agent, alpha,omega-dihydroxy-(ethylene ...
Plant waste materials from restaurants as the adsorbents for dyes / Iskorišćenje sirovog otpada iz restorana za adsorpciju boja
(Association of Chemical Engineers of Serbia, 2015)
This paper has demonstrated the valorization of inexpensive and readily available restaurant waste containing most consumed food and beverage residues as adsorbents for methylene blue dye. Coffee, tea, lettuce and citrus ...
Modelling of cations retention in ion chromatography with methanesulfonic acid as eluent
(Savez hemijskih inženjera, Beograd, 2017)
The two retention models, the linear solvent strength model (LSS) and the quadratic relationship, in addition to artificial neural network (ANN) approach, were compared in their ability to predict the retention behaviour ...
