Adsorption of Congo Red Dye Using Activated Carbon-Fe3O4 Composite
( Qatar University Press , 2023 , Conference Paper)Activated Carbon-Fe3O4 composites were synthesized using co-precipitation method and used in batch experiments to adsorb Congo red dyes. The effect of adsorbent dosage, temperature and initial dye concentration was ... -
Adsorption of textile dye onto modified immobilized activated alumina
( Elsevier Science B.V. , 2016 , Article)The study describes the synthesis of modified immobilized activated alumina (MIAA) and its application for the removal of textile dye from aqueous media. Immobilization was carried out by using the sol–gel method while ... -
Bio-sorption of toxic metals from industrial wastewater by algae strains Spirulina platensis and Chlorella vulgaris: Application of isotherm, kinetic models and process optimization
( Elsevier B.V. , 2021 , Article)The present study evaluates the effect of an acidic treatment on the improvement of the percentage removal of toxic metal (%TMrem) from wastewater by algae strains (Spirulina platensis (SP) and Chlorella vulgar (CV)) under ... -
Concurrent adsorption of cationic and anionic dyes from environmental water on amine functionalized carbon
( IWA Publishing , 2020 , Article)Amine functionalized carbon (AFC) was synthesized from raw oil fly ash and later utilized it for simultaneous removal of methyl orange (MO) and rhodamine 6G (Rh6G) pollutant dyes from aqueous medium. AFC was analyzed through ... -
Effective removal of lanthanum ions from aqueous solution using rice husk: Impact of experimental variables
( Desalination Publications , 2018 , Article)The focus of the present work is to optimize different experimental parameters such as nature of electrolyte, pH, amount of adsorbent, ions concentration, equilibration time, temperature, and operating mode. The effective ... -
Investigation of lanthanum impregnated cellulose, derived from biomass, as an adsorbent for the removal of fluoride from drinking water
( Elsevier Ltd , 2017 , Article)High concentrations of fluoride in drinking water can cause the disease fluorosis. Our scope goal is to develop an effective biopolymeric adsorbent for the removal of fluoride to below a specific safety limit set by the ... -
Kinetic, equilibrium and thermodynamic studies for adsorption of nickel ions onto husk of oryza sativa
( Desalination Publications , 2019 , Article)This research focus onto batch adsorption of nickel ions (Ni(II)) onto husk of Oryza sativa (HOS) from aqueous solution at room temperature. Several techniques such as Fourier transform infrared, scanning electron microscopy ... -
Mesoporous and high-surface-Area activated carbon from defatted olive cake by-products of olive mills for the adsorption kinetics and isotherm of methylene blue and acid blue 29
( Elsevier Ltd , 2020 , Article)The K2CO3 activation of defatted olive cake in N2 atmosphere was attempted for activated carbon (DOC-AC) preparation to test its ability for the adsorption of methylene blue (MB) and acid blue 29 (AB 29). The optimum conditions ... -
Natural and Low-Cost P. turgidum for Efficient Adsorption of Hg(II) Ions from Contaminated Solution: Isotherms and Kinetics Studies
( Springer , 2021 , Article)Mercury (II) ions (Hg(II)), a potent heavy metal water pollutant, was efficiently removed using a novel adsorbent prepared from Panicum turgidum roots by facile drying. The experimental conditions such as the solution pH, ... -
Potato Peels as an Adsorbent for Heavy Metals from Aqueous Solutions: Eco-Structuring of a Green Adsorbent Operating Plackett-Burman Design
( Hindawi Limited , 2019 , Article)Treatment of wastewater is becoming a concern of an increasing prominence. Trace amounts of toxic metalloids and heavy metals (HMs) would contaminate large volumes of water. Being present as traces, removal of these ... -
Removal of copper ions from aqueous solution using NaOH-treated rice husk
( Springer Nature , 2020 , Article)The present study investigates the removal of copper ions (Cu (II)) from aqueous solution using chemically treated rice husk (TRH). The chemical treatment was carried out using NaOH solution and the effect of contact time ...
