Dyes are growing to be a problematic class of pollutants to the environment. The disposal of
dyes in water resources has bad aesthetic and health effects, hence the need to remove …

Clay minerals and their modified derivatives have composed a large family of adsorbents
which can be used for the adsorption of most of the chemical contaminants from aqueous …

Eco-friendly adsorbent of chitosan–montmorillonite/polyaniline (CH–Mt/PANI)
nanocomposite was synthesized by the intercalation of CH into Mt through ion-exchange …

This study investigates the potential use of activated carbon prepared from coffee waste
(CW) as an adsorbent for the removal of congo red dye from aqueous solution. The oxygen …

In this work, composite hydrogel beads based on magnetic bentonite/carboxymethyl
chitosan/sodium alginate (Mag-Ben/CCS/Alg) were fabricated and their ability to adsorb …

Dyes are an important class of pollutants, and can even be identified by the human eye.
Disposal of dyes in precious water resources must be avoided, however, and for that various …

Applications of second-order kinetic models to adsorption systems were reviewed. An
overview of second-order kinetic expressions is described in this paper based on the solid …

The intraparticle diffusion model (IPD) proposed by Weber and Morris has been widely
applied for the analysis of adsorption kinetics. In this work, the characteristic curves based …

Biochars were prepared from feedstocks pinewood and pig manure. Biochar microparticles
obtained through grinding were evaluated for the removal of emerging contaminant …

Low adsorption capacity of natural clay minerals is a key technical and economical issue
which limits their industrial application as low cost absorbents for removal of hazardous …
