Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier Science Sa, Lausanne, 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 ...
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 ...
Adsorption of lipase from Candida rugosa on multi walled carbon nanotubes
(Elsevier Science Inc, New York, 2013)
In this work lipase from Candida rugosa was adsorbed on unmodified surface of multi walled carbon nanotubes (raw-MWCIsIT). The effects of immobilization time, initial enzyme concentration and buffer ionic strength on enzyme ...
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 ...
Kinetics, thermodynamics, and structural investigations on the removal of Pb2+, Cd2+, and Zn2+ from multicomponent solutions onto natural and Fe(III)-modified zeolites
(Springer, New York, 2015)
The adsorption of Pb2+, Cd2+, and Zn2+ from equimolar multicomponent solutions onto natural and Fe(III)-modified zeolites was studied by batch experiments in order to determine the influence of the competitive effect on ...
The adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto natural zeolites and clays: Clinoptilolite, bentonite and kaolin
(Elsevier, Amsterdam, 2013)
In this study, adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto clinoptilolite modified with sorbed metallic cations (Cu(II), Zn(II), Ni(II) or Mn(II)) have been probed. Natural ...
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 ...
Arsenic removal by copper-impregnated natural mineral tufa part II: a kinetics and column adsorption study
(Springer Heidelberg, Heidelberg, 2019)
This batch and column kinetics study of arsenic removal utilized copper-impregnated natural mineral tufa (T-Cu(A-C)) under three ranges of particle size. Non-competitive kinetic data fitted by the Weber-Morris model and ...
Preparation and Characterisation of Novel Biodegradable Material Based on Chitosan and Poly(Itaconic Acid) as Adsorbent for Removal of Reactive Orange 16 Dye from Wastewater
(Springer Int Publishing Ag, Cham, 2015)
Environmental protection has been a topic of great interest in recent years. Discharging azo dyes in aquatic systems contaminates water and causes serious ecological problems. Azo dyes are bio-accumulative, and, due to ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The concept of higher-order frequency response functions (FRFs), which is based on Volterra series representation of nonlineral systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
