Arsenic removal by copper-impregnated natural mineral tufa part II: a kinetics and column adsorption study
(Springer Heidelberg, Heidelberg, 2019)
This batch and column kinetics study of arsenic removal utilized copper-impregnated natural mineral tufa (T-Cu(A-C)) under three ranges of particle size. Non-competitive kinetic data fitted by the Weber-Morris model and ...
Physico-chemical, structural, and adsorption properties of amino-modified starch derivatives for the removal of (in)organic pollutants from aqueous solutions
(International Journal of Biological Macromolecules, 2023)
In this study, an environmentally sustainable process of crystal violet, congo red, methylene
blue, brilliant green, Pb2+, Cd2+, and Zn2+ ions adsorption from aqueous solutions onto aminomodified starch derivatives was ...
Immobilization of Candida rugosa lipase by adsorption onto biosafe meso/macroporous silica and zirconia
(Elsevier B.V., 2015)
Lipase from Candida rugosa was immobilized by adsorption onto laboratory prepared supports, silica SBA-15 and zirconia. The adsorption process was studied as a function of pH in terms of percent of adsorbed lipase, enzyme ...
Removal of mineral oil and wastewater pollutants using hard coal
(Association of Chemical Engineers of Serbia, 2009)
This study investigates the use of hard coal as an adsorbent for removal of mineral oil from wastewater. In order to determine the efficiency of hard coal as an adsorbent of mineral oil, process parameters such as sorption ...

Removal of the As(V) and Cr(VI) from the Water Using Magnetite/3D-Printed Wollastonite Hybrid Adsorbent
(International Institute for the Science of Sintering (IISS), 2022)
In this study, the structure, morphology and composition of the synthesized magnetite/3D-printed wollastonite (3D_W/M) composite were characterized, and its adsorption performance with respect to As(V) and Cr(VI) were ...
Adsorption of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from water onto modified multi-walled carbon nanotubes, carbon cryogel, and carbonized hydrothermal carbon
(Environmental Science and Pollution Research, 2022)
Carbon materials of different structural and textural properties (multi-walled carbon nanotubes, carbon cryogel, and carbonized hydrothermal carbon) were used as adsorbents for the removal of estrone, 17 beta-estradiol, ...
Removal of trivalent chromium from aqueous solutions by natural clays: Valorization of saturated adsorbents as raw materials in ceramic manufacturing
(Elsevier, 2023)
Kaolinite/illite (KUb) and sepiolite (SEP) clays were used to study Cr(III) adsorption removal from aqueous solutions so that they could be utilized after saturation for ceramic manufacturing. SEP had a larger specific ...
Adsorption of arsenate on iron(III) oxide coated ethylenediamine functionalized multiwall carbon nanotubes
(Elsevier Science Sa, Lausanne, 2012)
New criteria in assessing the quality of drinking water reduced the maximum permissible concentration of arsenic from 50 mu g L-1 to 10 mu g L-1 and set a requirement for the development of new technologies for arsenic ...
