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, ...
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 ...
Adsorptive pretreatment of waste cooking oil using quicklime for two-step biodiesel production
(Valladolid : The lnstitute of Bioeconomy of University of Valladolid, 2023)
Biodiesel, a mixture of fatty acid methyl esters (FAME), is an excellent non-toxic, and biodegradable substitute for mineral diesel fuels produced from crude oil. It is made from renewable sources by transesterification ...
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 ...
Revealing the adsorption mechanism of copper on hemp-based materials through EDX, nano-CT, XPS, FTIR, Raman, and XANES characterization techniques
(Elsevier B.V., 2022)
Hemp-based materials have been recently proposed as adsorbents for metals present in aqueous solutions using adsorption-oriented processes. This study aims to reveal the adsorption mechanism of materials prepared from hemp ...
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 ...
Removal of Estrone, 17 beta-Estradiol, and 17 alpha-Ethinylestradiol from Water by Adsorption onto Chemically Modified Activated Carbon Cloths
(Korean Fiber Soc, Seoul, 2020)
This paper explores the applicability of unmodified and chemically modified activated carbon cloths (ACCs) for the removal of estrone, 17 beta-estradiol, and 17 alpha-ethinylestradiol from water. In order to examine the ...
Multifunctional use of magnetite-coated tuff grains in water treatment: Removal of arsenates and phosphates
(Elsevier Science Bv, Amsterdam, 2019)
Natural filtration material tuff (T) was modified by coating with nano-sized magnetite. The grain fraction of 0.6-1.9 mm was submitted to hydrothermal synthesis of magnetite. Thus formed magnetite modified tuff (MMT) was ...
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 ...
Advanced thermodynamic approach to adsorption of charged adsorbates from aqueous electrolyte solutions
(Elsevier B.V., 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 ...
