Sinthesis and Characterization of Hydroxyapatite and Fluorapatite Powders
(Belgrade : ETRAN SocietyBelgrade : Academic Mind, 2019)
The biomaterial powders of hydroxyapatite (HAp)
and fluorapatite (FAp) were synthesized by a hydrothermal
method. Powders were analyzed by energy-dispersive X-ray
spectroscopy (EDS), field emission scanning electron ...
Removal of Pb2+ from aqueous solution by P(HEA/IA) hydrogels
(Savez hemijskih inženjera, Beograd, 2016)
A series of poly(2-hydroxyethyl acrylate-co-itaconic acid), P(HEA/IA), hydrogels with different HEA/IA ratio, were synthesized using free radical crosslinking/copolymerization and investigated as sorbents for Pb2+ from ...
