Study of Water Vapour Adsorption on Sandwich-Type CuO/NaX Adsorbent–Catalysts

open access: yesAdsorption Science & Technology, 2010
Experimental data show that the adsorbent–catalyst CuO/NaX is hydrophilic with a similar water vapour adsorption capacity and adsorption rate to zeolite NaX. Equilibrium parameters were best described by a Freundlich-like equation. BET studies and Kelvin

Bioadsorption of a reactive dye from aqueous solution by municipal solid waste

open access: yesBiotechnology Reports, 2015
The biosorbent was obtained from municipal solid waste (MSW) of the Mostaganem city. Before use the MSW was dried in air for three days and washed several times.

The Utilization of Silica–Lignin Composite as a Green Adsorbent for Cobalt and Lead Metal Ions in Aqueous Phase

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in environmental waste can pollute the environment and disrupt human health if not managed properly. Heavy metal contamination from industrial waste, particularly cobalt (Co) and lead (Pb), poses serious environmental and health risks due to their toxicity, persistence, and bioaccumulative nature.

Simultaneous adsorption of Ni(II) and Mn(II) ions from aqueous solution unto a Nigerian kaolinite clay

open access: yesJournal of Materials Research and Technology, 2014
An unmodified Nigerian kaolinite clay (UAK) was utilized as a low-cost adsorbent for the removal of Ni(II) and Mn(II) ions from a binary solution of both metal ions.

Preparation of MOEAMCl and MAAm Based Hydrogels and Effective Use in Anionic Dye Adsorption

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.
ABSTRACT In this study, hydrogels based on [2‐(Methacryloyloxy)ethyl]trimethylammonium chloride (MOEAMCl) and methacrylamide (MAAm) were synthesized for the removal of anionic dyes from aqueous solutions. Following detailed characterization, the use of hydrogels for methyl orange (MO) adsorption was investigated.

Kinetics of the Adsorption of Copper and Lead Ions from Aqueous Solution on to WD-ekstra Activated Carbon

open access: yesAdsorption Science & Technology, 2002
The kinetics of the adsorption of Cu 2+ and Pb 2+ ions from aqueous solution on to WD-ekstra activated carbon was studied by batch methods. Such adsorption processes proceeded in two stages: an initial rapid stage followed by a slower one.

Kinetic, equilibrium and thermodynamic investigations of Ni(II), Cd(II), Cu(II) and Co(II) adsorption on barley straw ash

open access: yesWater Resources and Industry, 2014
This work reports the application of a straw ash from barley as a novel bioadsorbent for the removal of several heavy metals: Ni(II), Cd(II), Cu(II), and Co(II).

Study on iron anchoring methods for magnetic biochar: Characterization, functional mechanism, and RBBR dye removal

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Magnetic biochar (MBC) is a novel bio‐metallic composite material with high potential in sustainable water cleaning. Iron anchoring is critical in forming iron‐based MBC and will fundamentally impact its characteristics and functionality in dye removal applications. However, the mechanism is not well‐revealed.

Retention characteristics of acetochlor in soils collected from different depths in relation to soil properties (Žitný ostrov area, SW Slovakia)

open access: yesSoil and Water Research, 2014
Determination of the sorption-desorption of herbicides within soil profile is one of the first steps in predicting their leaching potential. Batch experiments were performed to evaluate the influence of soil properties on acetochlor retention.
