Hexavalent chromium removal from aqueous medium by activated carbon prepared from peanut shell: Adsorption kinetics, equilibrium and thermodynamic studies
Activated carbon was prepared from peanut shell by chemical activation with KOH. Unoxidized activated carbon was prepared in nitrogen atmosphere which was then heated in air at a desired temperatureExpand
Efficient techniques for the removal of toxic heavy metals from aquatic environment: A review
Abstract The controversy related to the environment pollution is increasing in human life and in the eco-system. Especially, the water pollution is growing rapidly due to the wastewater dischargeExpand
Activated lignin-chitosan extruded blends for efficient adsorption of methylene blue
Abstract This work investigates the production of activated lignin-chitosan extruded (ALiCE) pellets with controlled particle size distribution (almost spherical: dp ∼500–1000 μm) for efficientExpand
Kinetics, thermodynamics and isotherm modeling for removal of nitrate from liquids by facile one-pot electrosynthesized nano zinc hydroxide
Abstract This study deals with the removal of nitrate from water by electrocoagulation process using zinc and stainless steel as anode and cathode respectively. The optimizations of variousExpand
Novel Metal-Organic Framework (MOF) Based Composite Material for the Sequestration of U(VI) and Th(IV) Metal Ions from Aqueous Environment.
The excellent adsorption capacity and the response to the magnetic field made this novel material an auspicious candidate for environmental remediation technologies. Expand
Fabrication and characterization of Gum arabic-cl-poly(acrylamide) nanohydrogel for effective adsorption of crystal violet dye.
A novel nanohydrogel of gum arabic with acrylamide has been fabricated using microwave synthesis for adsorption of noxious crystal violet dye from aqueous medium using Langmuir model. Expand
Desorption of Methylene blue dye from brown macroalga: Effects of operating parameters, isotherm study and kinetic modeling
Abstract In this study, desorption of Methylene blue (MB) dye from brown macroalga, Nizamuddinia zanardinii was investigated. Batch experiments were conducted to determine the effects of variousExpand
Guar gum-crosslinked-Soya lecithin nanohydrogel sheets as effective adsorbent for the removal of thiophanate methyl fungicide.
Results showed that neutral pH favoured the adsorption process andKinetics results were indicative of the physical interactions between the thiophanate methyl and GG-crosslinked-SY NHS surface, and Thermodynamic results have shown the spontaneous and endothermic adsorptive process. Expand
Adsorptive performance of MOF nanocomposite for methylene blue and malachite green dyes: Kinetics, isotherm and mechanism.
The Fe3O4@AMCA-MIL-53(Al) nanocomposite was an outstanding material for the removal of dyes from aqueous environment and was well fitted to Langmuir isotherm and pseudo-first-order kinetics models. Expand
Transformation pathways and fate of engineered nanoparticles (ENPs) in distinct interactive environmental compartments: A review.
This review focus on ENPs transformations in the various environmental compartments with the utmost importance to study the behavior of transformed ENPs to understand their environmental fate, bioavailability, and mode of toxicity. Expand
