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 ...
Physico-chemical, structural, and adsorption properties of amino-modified starch derivatives for the removal of (in)organic pollutants from aqueous solutions
(Elsevier B.V., 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 amino-modified starch derivatives was ...
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 ...
Advanced thermodynamic approach to adsorption of charged adsorbates from aqueous electrolyte solutions
(Elsevier B.V., 03-2024)
This study present estimation of the thermodynamic parameters and the influence of ionic activity coefficient on the thermodynamic equilibrium constant of adsorption of phosphates on fly ash. The adsorption was conducted ...
Structural and surface modification of highly ordered alumina for enhanced removal of Pb2+, Cd2+ and Ni2+ from aqueous solution
(Desalination Publ, Hopkinton, 2020)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) alumina doped with iron oxide, and subsequently modified with (3-aminopropyl)triethoxysilane (APTES), FeAl2O3 and FeAl(2)O(3)APTES, was used for ...
Comparative study of cu(2+) adsorption on a zeolite, a clay and a diatomite from Serbia
(Applied Clay Science, 2009)
The adsorption of a zeolite, clay and diatomite from Serbia toward aqueous Cu2+ ions was studied, at different pH. The adsorbents were characterized with respect to phase composition, specific surface area and point of ...
Spirulina-based carbon bio-sorbent for the efficient removal of metoprolol, diclofenac and other micropollutants from wastewater
(Elsevier, 2022)
This study proposes an efficient activated spirulina-based carbon material (ASBCM800) with an extremely high specific surface area (2211 m2 g−1) to eliminate a wide range of micropollutants (MPs) frequently detected in ...
Revalorization of Cotton and Cotton/Elastane Knitted Fabric Waste
(Korean Fiber Society, 2023)
The present paper demonstrates a simple way for revalorization of differently softened cotton and cotton/elastane knitted fabric waste collected from the textile industry. Such waste was used as an adsorbent for Congo Red ...
