This study investigated Ni (II) ion adsorption from aqueous solution on activated carbons
obtained by chemically modifying the surface with the oxidizing agents nitric acid and …

Activated carbon adsorption processes are frequently identified as the best available
technology for the removal of industrial pollutants such as pesticides, chlorinated organic …

Laboratory studies were performed with the surface water taken from the Ömerli Reservoir in
Istanbul. Adsorption and desorption of natural organic matter (NOM) were studied with four …

Adsorption of Cr (III), Mn (II), Cu (II) and Zn (II) on an oxidized activated carbon cloth was
studied. Its surface chemistry was characterized by potentiometric titration. This technique …

The mesoporous graphitic carbon nitride (mpg‐C3N4/r, r was defined as the initial
silica/dicyandiamide mass ratio) was successfully synthesized by heating the mixture of …

In this work, unburnt coal (UC) in bottom ash from coal-fired power plants was soaked in
KOH solution and activated for 1 h at 780° C. The yield of activated carbons varied from 47.8 …

Three activated carbons and two chars made from low rank coal were evaluated in terms of
their ability to remove the organic compound 4-nitrophenol (4-NP) and natural organic …

Ammonia adsorption was studied under dynamic conditions, at room temperature, on
activated carbons of different origins (coal-based, wood-based and coconut-shell-based …

In the adsorption process, the surface area, pore and particle size distribution and the
chemical structure of the solid and the type of adsorbent are of vital importance. Activated …

In this study, the N-doping of biomass-activated carbon with dicyandiamide was performed
via an ultrasonic method and a redox method. BET, SEM, EDS, FT-IR and XPS were used to …
