Hg(II) removal from water by chitosan and chitosan derivatives: A review
(Elsevier Science, 2009-08-15)
Mercury (Hg) is one of the most toxic heavy metals commonly found in the global environment. Its toxicity is related to the capacity of its compounds to bioconcentrate in organisms and to biomagnifie through food chain. A ...
Characterization of chitosan/ caseinate films
(John Wiley & Sons Inc, 2008-01)
Films made from sodium caseinate and/or chitosan, using glycerol as plasticizer, were prepared by casting from aqueous solutions. Films cryo-fractured surfaces were examined by SEM. FTIR spectra of the chitosan/caseinate ...
Electrophoretic deposition of chitosan/Bioglass® and chitosan/Bioglass®/TiO2 composite coatings for bioimplants
(Elsevier, 2016-09)
Electrophoretic deposition (EPD) method has been developed for the fabrication of chitosan/Bioglass and chitosan/Bioglass/TiO2 composite coatings on stainless steel substrates for biomedical applications. Microstructure, ...
Adsorption of arsenic onto films based on chitosan and chitosan/nano-iron oxide
(Elsevier Science, 2020-12)
Films made from neat chitosan and chitosan with magnetic nanoparticles (MNPs) were tested as adsorbents of arsenate ions. Sorption equilibrium and sorption kinetics studies are reported, including different models applied ...
Fabrication of Green Diatomite/Chitosan-Based Hybrid Foams with Dye Sorption Capacity
(Molecular Diversity Preservation International, 2020-08-25)
The latest tendency of the scientific community regards the development of different classes of green materials able to solve pollution problems caused by industrial and human activity. In this paper, chitosan and diatomite ...
Dodecenylsuccinic anhydride modified chitosan hydrogels for the sustained delivery of hydrophobic drugs: The case of thymol buccal delivery
(John Wiley & Sons Inc., 2022-01-05)
Chitosan polymer as a bioactive carrier has an emerging importance due to its great versatility. Many strategies are reported for enhancing its properties. Herein, chitosan hydrogels modified by dodecenylsuccinic anhydride ...
Antibacterial Effect of Chitosan–Gold Nanoparticles and Computational Modeling of the Interaction between Chitosan and a Lipid Bilayer Model
(Multidisciplinary Digital Publishing Institute, 2020-11-25)
Pathogenic bacteria have the ability to develop antibiotic resistance mechanisms. Their action consists mainly in the production of bacterial enzymes that inactivate antibiotics or the appearance of modifications that ...
Chitosan influence on glucose and calcium availability from yogurt: In vitro comparative study with plants fibre
(Elsevier, 2008-11)
Since chitosan complies with the definition of dietary fibre is necessary to study the interaction of this biopolymer with nutrients. Yogurt with fortified chitosan and different types of plants fibres like wheat, bamboo, ...
Comparison of the Performance of Chitosan and a Cationic Polyacrylamide as Flocculants of Emulsion Systems
(Springer Heidelberg, 2001-01)
Food industries contribute significantly to the pollution of water streams. Oil in wasterwaters must be removed to prevent fouling of process equipment, to reduce interference with subsequent water-treatment units, and to ...
The Water-Soluble Chitosan Derivative, N-Methylene Phosphonic Chitosan, Is an Effective Fungicide against the Phytopathogen Fusarium eumartii
(Korean Soc Plant Pathology, 2021-12)
Chitosan has been considered an environmental-friend-ly polymer. However, its use in agriculture has not been extended yet due to its relatively low solubility in water. N-Methylene phosphonic chitosan (NMPC) is a water-soluble ...
