Adsorptive properties of silica gel for biodiesel refining
(American Chemical Society, 2008-11)
The refining of biodiesel by adsorption over silica gel was assessed. Silica gel samples were used for the adsorption of glycerol and monoglycerides. Room-temperature isotherms for the adsorption of glycerol were measured ...
Hexavalent chromium removal in contaminated water using reticulated chitosan micro/nanoparticles from seafood processing wastes
(Elsevier, 2015-07)
Chitosan particles (CH) were obtained from seafood processing wastes (shrimp shells) and physicochemically characterized; deacetylation degree of CH was measured by Infrared Spectroscopy (FTIR) and potentiometric titration; ...
Insights of competitive adsorption on activated carbon of binary caffeine and diclofenac solutions
(Academic Press Ltd - Elsevier Science Ltd, 2021-01-15)
A commercial activated carbon (AC), obtained from peanut shells, was characterized and tested as adsorbent forthe removal of the pharmaceutical products caffeine (CF) and diclofenac (DIC), which were used as modelemerging ...
Advances in the adsorptive particulate flotation process
(09/18/2003)
The removal of contaminants from liquid effluents by the adsorptive particulate flotation (APF) process, including new adsorbents and flotation devices, are reported. Herein, contaminants are adsorbed (and/or absorbed) ...
Using activated carbon as bioadsorvent for the residual waters treatment: a reviewUSE OF ACTIVATED CHARCOAL AS BIO-ADSORBENT FOR TREAMENT OF RESIDUAL WATERS: A REVIEW
(Universidade Federal de Mato Grosso, 2021)
Synthesis and adsorption behavior of mesoporous alumina and Fe-doped alumina for the removal of dominant arsenic species in contaminated waters
(Elsevier Ltd, 2019-02)
Ordered mesoporous Al 2 O 3 and Fe-Al 2 O 3 materials were synthesized at room temperature by an easy and environmentally friendly self-assembly sol-gel route, to be tested for arsenic removal. Solid samples were thoroughly ...
Electronic and magnetic properties of the adsorption of As harmful species on zero-valent Fe surfaces, clusters and nanoparticules
(Elsevier Science, 2019-01-28)
A systematic theoretical study of the adsorption of H3AsO3 and H3AsO4 acids on Fe nanoparticles was carried out using the Density Functional Theory (DFT). Different sizes of zero-valent iron particles and also the two most ...
Application of chitosan in removal of molybdate ions from contaminated water and groundwater
(Elsevier, 2018-01)
Water pollution by heavy metals represents a serious problem around the world. Among various treatment techniques for water remediation, adsorption is an effective and versatile method due to the low cost, effectiveness ...
Adsorption of hexavalent chromium in an industrial site contaminated with chromium in Mexico
(Springer International Publishing AG, 2014-05)
This work presents the problems left by a company that manufactured chrome-plated products for 20 years, without controlling its waste, until it was closed by the authorities in 1978. The raw material used was chromite ...
Organo-montmorillonites as adsorbent materials for thiophanate-methyl removal: adsorption-desorption studies and technological applications
(Elsevier, 2020-08-06)
Thiophanate-methyl (TM) is a fungicide widely used in post-harvest treatment of pears and apples. The wastewater of this treatment usually is discharged to the natural rivers without treatment, with the consequent concern ...
