Aqueous Pb sorption by synthetic and natural apatite: Kinetics, equilibrium and thermodynamic studies
(Chemical Engineering Journal, 2010)
Natural apatites represent a cost effective soil amendment, which can be used for in situ reduction of lead bioavailability and mobility. In our previous work, we selected Lisina apatite (LA) as a promising natural mineral ...
Efficient arsenic removal by cross-linked macroporous polymer impregnated with hydrous iron oxide: Material performance
(Chemical Engineering Journal, 2015)
Optimization of the synthesis of cross-linked macroporous polymer impregnated with hydrous iron oxide and post-process of obtained material by application of freeze/drying technique, produces high performance adsorbent ...
Hydrogel based on chitosan, itaconic acid and methacrylic acid as adsorbent of Cd2+ ions from aqueous solution
(Chemical Engineering Journal, 2010)
A hydrogel has been synthesized by ionic crosslinking of chitosan (Ch) with itaconic acid (IA), followed by a free radical polymerization and crosslinking of Ch/IA network by adding methacrylic acid and the crosslinker. ...
Study of factors affecting Ni2+ immobilization efficiency by temperature activated red mud
(Chemical Engineering Journal, 2011)
The waste red mud, remaining in remarkable quantities after the digestion of bauxite ores following the Bayer process, contains number of voluble minerals with excellent sorption properties towards aqueous heavy metals. ...
Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Chemical Engineering Journal, 2014)
An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system ...
Effect of acid treatment on red mud properties with implications on Ni(II) sorption and stability
(Chemical Engineering Journal, 2014)
Red mud, a heterogeneous mineral waste from aluminum industry, can be beneficially utilized as a sorbent. High alkalinity and the amount of water soluble ions can limit some of its applications. This studys aim was to ...
The influence of citrate anion on Ni(II) removal by raw red mud from aluminum industry
(Chemical Engineering Journal, 2013)
The removal of Ni(II) from aqueous solutions by raw red mud powder was studied in the absence and in the presence of citrate ligand, as a function of process parameters. Using lower initial Ni(II) concentration (10(-3) ...
Analysis and comparison of mass transfer phenomena related to Cu2+ sorption by hydroxyapatite and zeolite
(Chemical Engineering Journal, 2013)
Zeolite and hydroxyapatite (HAP) are well-known sorbent materials, with high capacities for removal of toxic heavy metals. In this study, the influence of process parameters onto kinetics of Cu2+ sorption by zeolite and ...
Rinsed and thermally treated red mud sorbents for aqueous Ni2+ ions
(Chemical Engineering Journal, 2010)
Red mud, an abundant industrial waste from alumina industry, represents a rich source of various metal oxides, mainly of Fe2O3 Al2O3 and SiO2. In this study, the rinsed Bosnian red mud (RBRM) was evaluated as an economical, ...
Synthesis, characterization and controlled release of cephalexin drug from smart poly(2-hydroxyethyl methacrylate/poly(alkylene glycol)(meth)acrylates hydrogels
(Chemical Engineering Journal, 2010)
In this work, novel hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and different poly(alkylene glycol)(meth)acrylates (BIS) were prepared by radiation-induced copolymerization. The influence of different BIS types ...
