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 …

For the removal and separation of wastewater pollutants, one widely used technique is
adsorption. Different materials have been used as adsorbents. Among several adsorbents …

Concerns regarding microplastics pollution and their potential to concentrate and transport
organic contaminants in aquatic environments are growing in recent years. Sorption of …

Microplastics (MPs) and heavy-metal contamination in freshwater is an increasing concern.
Fe, Mn, Pb, Zn, Cr, and Cd are common heavy metals that can easily flow into rivers causing …

This paper investigates the adsorption performance of spent tea leaves (STL) modified with
polyethylenimine (PEI) on two anionic dyes, namely Reactive Black 5 (RB5) and Methyl …

Adsorption is recognized as one of the most promising methods for heavy metal removal
from contaminated water. However, the adsorption efficiency often decreases because of …

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 …

The effect of temperature on the equilibrium adsorption of methylene blue dye from aqueous
solution using carbon nanotubes was investigated. The equilibrium adsorption data were …

The adsorption of methyl orange onto multiwalled carbon nanotubes (MWCNTs) from
aqueous solutions was studied, in which the influence of contact time, dosage, temperature …

The removal of azo dye from wastewater is urgent due to its massive discharge from various
industries and high toxicity. Adsorption is an efficient removal method, but it is limited by the …
