Equilibrium and kinetics study on hexavalent chromium adsorption onto diethylene triamine grafted glycidyl methacrylate based copolymers
(Elsevier Science Bv, Amsterdam, 2012)
Two porous and one non-porous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were prepared by suspension copolymerization and functionalized with diethylene triamine [abbreviated ...
Purification technologies for crude biodiesel obtained by alkali-catalyzed transesterification
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
For commercial application, the ester product of alkali-catalyzed transesterification of vegetable oil or animal fats should be refined after glycerol separation by settling to fulfill the biodiesel standard specifications. ...
Antioxidant edible films based on chitosan and starch containing polyphenols from thyme extracts
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to analyse the antioxidant activity of different polymeric matrices based on chitosan and starch, incorporating a thyme extract (TE) rich in polyphenols. TE provided the films with remarkable ...
