Implementation of integrated adsorption and biological process in wastewater treatment for permanent dye removal and its subsequent decontamination
(Desalination Publ, Hopkinton, 2019)
The use of the microwave-activated sugar beet pulp as an alternative adsorbent material in combination with biological processes has been applied for the colored wastewater treatment. The maximum adsorption capacity of the ...
Utilization of agro-industrial waste for removal of copper ions from aqueous solutions and mining-wastewater
(Elsevier Science Inc, New York, 2019)
In this study, unmodified lemon peel, as agro-industrial waste, was used to investigate removal efficiency of copper ions from aqueous solutions and mining wastewater. The effects of solution pH, adsorption time, metal ion ...
Modification of multi-wall carbon nanotubes for the removal of cadmium, lead and arsenic from wastewater
(Inst Materials Physics, Bucharest, 2013)
Multi-wall carbon nanotubes (MWCNTs) was functionalized with 6-arm amino polyethylene glycol (PEG), and synthesized PEG-MWCNTs was used as adsorbent in order to study adsorption characteristics with respect to Cd(II), ...
Adsorption of Candida rugosa lipase onto alumina: effect of surface charge
(Serbian Chemical Society, 2015)
The impact of the surface charge of alumina supports on the adsorption of Candida rugosa lipase was investigated in terms of the zeta potentials of the adsorption partners. The lipase adhered onto alumina with similar ...
Controllable synthesis of Fe3O4-wollastonite adsorbents for efficient heavy metal ions/oxyanions removal
(Springer Heidelberg, Heidelberg, 2019)
Iron oxide, in the form of magnetite (MG)-functionalized porous wollastonite (WL), was used as an adsorbent for heavy metal ions (cadmium and nickel) and oxyanions (chromate and phosphate) removal from water. The porous ...
Further insight into the mechanism of heavy metals partitioning in stormwater runoff
(Academic Press Ltd- Elsevier Science Ltd, London, 2016)
Various particles and materials, including pollutants, deposited on urban surfaces are washed off by stormwater runoff during rain events. The interactions between the solid and dissolved compounds in stormwater runoff are ...
Binary adsorption of nickel and zinc from aqueous solutions onto the Serbian natural clinoptilolite
(Taylor & Francis Inc, Philadelphia, 2016)
Sorption of the Zn2+ and Ni2+ ions by the Na+-enriched natural clinoptilolite (Na-CLI) from aqueous solutions containing both Zn2+ and Ni2+ ions at a range of concentrations has been studied at 298, 308, and 318K. It was ...
Polyaniline stabilization of magnetic particles and immobilization of alpha-amylase
(Savez hemijskih inženjera, Beograd, 2018)
Magnetic particles (MAG), obtained by standard procedure of coprecipitation of Fe2+ and Fe3+ in an excess of ammonia, and polyaniline modified magnetic particles MAG-PANI were used as carriers for immobilization of a-amylase ...
Ultrasonic assisted arsenate adsorption on solvothermally synthesized calcite modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier, Amsterdam, 2014)
A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 ...
Removal of a Cationic Dye from Aqueous Solution by Microwave Activated Clinoptilolite-Response Surface Methodology Approach
(Springer International Publishing Ag, Cham, 2014)
Natural clinoptilolite from Zlatokop deposit, Serbia, was activated by microwave irradiations (10 min, 550 W) and its adsorptive efficiency for removal of crystal violet (CV) dye from aqueous solution was investigated. The ...
