Biogenic modified silica as a sorbent of cadmium ions: Preparation and characterization
(TAYLOR & FRANCIS LTD, 2009)
This work describes the preparation and characterization of biogenic modified silica from rice hull ash and its use as a sorbent of cadmium ions. Thus, an agro-industrial residue has been used to produce a new adsorbent ...
A comparative study of two nanosubstrates for the on-line solid phase extraction of antimony by FI-HG-AAS
(Elsevier Science, 2016-09)
Nanoporous carbon (NPC) prepared frommetal organic frameworks (MOFs)was studied to serve as a sorbent forpreconcentrating Sb(III) at trace levels. The performance of NPC regarding sensitivity, enrichment factor, ...
Utilização do lodo de esgoto como adsorvente para remoção de cor em efluente têxtil
(Universidade Tecnológica Federal do ParanáFrancisco BeltraoBrasilEngenharia AmbientalUTFPR, 2018-11-27)
Due to the large-scale generation of sewage sludge and the concern regarding the disposal of effluents from the textile industry that have the presence of dyes in their composition, this work was developed. The objective ...
A new rotating-disk sorptive extraction mode, with a copolymer of divinylbenzene and N-vinylpyrrolidone trapped in the cavity of the disk, used for determination of florfenicol residues in porcine plasma
(Microextraction Techniques, 2014)
A novel extraction approach was developed based
on rotating-disk sorptive extraction (RDSE). In this approach
the rotating-disk extraction device consists of a Teflon disk,
with a cavity that is loaded with a commercial ...
Cassava Husk Powder as an Eco-Friendly Adsorbent for the Removal of Nickel (II) Ions
(Springer Nature, 2022)
Here, the potential of cassava husk powder as a ecofriendly bio-sorbent of nickel (Ni) ions in aqueous media was presented. This bio-material was characterized as sorbent using several physical properties and analytical ...
Aplicación de quitosano como fase sorbente de origen natural en la microextracción por sorción en disco rotatorio (RDSE) de triclosán y metiltriclosán desde muestras acuosas
(Universidad de Chile, 2022)
Recientemente, las fases sorbentes de origen natural emergen como una alternativa verde para la preparación de muestras con ventajas significativas sobre las fases tradicionales. Entre los materiales utilizados destacan ...
Zn supported on Zr modified mesoporous SBA-15 as sorbents of pollutant precursors contained in fossil fuels: Si/Zr ratio effect
(Elsevier, 2019)
The adsption processes have become an additional alternative to hydrotreatment processes of oilderived
middle distillates. The crucial point is the type of adsorbent employed. SBA-15 mesoporous materials were used to ...
