The release of colored wastewater from industries into surface water bodies creates
undesirable consequences to the marine ecosystem and human beings owing to its …

Adsorption is one of the oldest and extensively studied techniques for water and wastewater
treatment. As a surface phenomenon, adsorption efficiency relies heavily on the surface …

The purpose of this research was to improve the sorption ability of Pb and Cd by promoting
the ion exchange and precipitation capacity of biochar. The adsorption performance and …

Mesoporous activated carbon was prepared using a hydrochar derived from coconut shell
waste through hydrothermal carbonization and NaOH chemical activation process …

The massive generation of medical waste (MW) results in a series of environmental, social,
and ecological problems. Pyrolysis is one such approach that has attracted more attention …

The choice of activating agent for the thermochemical production of high-grade activated
carbon (AC) from agricultural residues and wastes, such as feedstock, requires innovative …

Recently many researchers have proved the capability of agricultural solid wastes as
adsorbents to remove many types of pollutants including dyes. This review represents the …

New magnetic iron oxide (Fe3O4)/activated charcoal (AC)/β-cyclodextrin (CD)/sodium
alginate (Alg) polymer nanocomposite materials were prepared by direct mixing of the …

Activated carbons (ACs) of coconut shell produced by NaOH activation at impregnation
ratios of NaOH: char (w/w) equal to 1: 1 (AC-1), 2: 1 (AC-2) and 3: 1 (AC-3) were prepared …

In this article, the use of low-cost adsorbents for the removal of methylene blue (MB) from
solution has been reviewed. Adsorption techniques are widely used to remove certain …
