Heavy Metal Ions Adsorption on Chitosan-Magnetite Microspheres
Composite chitosan-magnetite microparticles (Fe-Cc) were evaluated as a new adsorbent for cobalt and nickel ion separation from aqueous solutions. Sorption batch experiments were conducted for optimizing the pH, initial target ion concentration and adsorbent amount. The experimental data were fitted using Langmuir, Freundlich, and respectively DubininRadushkevich isotherm models. The Langmuir m...
متن کاملFluoride adsorption on carboxylated aerobic granules containing Ce(III).
Aerobic granules (AG) were carboxylated and Ce(III) was incorporated to obtain modified granuels (Ce(III)-MAG) for removal of fluoride from aqueous solutions. The Ce(III)-MAG was characterized by SEM, FTIR, XRD and pH(pzc), and the introduction of carboxyl groups and Ce(III) was confirmed. The adsorption capacity of Ce(III)-MAG for fluoride was 45.80 mg/g at neutral pH, an increase of 359% comp...
متن کاملWater adsorption isotherms of lipids.
Hydration of bilayer lipids is a fundamental property of biological membranes. The available database of lipid hydration isotherms is fitted over the entire range of water activities by using a statistical mechanical approach that is an extension of the common Brunauer-Emmett-Teller model, to include differential energies of association for water molecules beyond the first strongly bound layer....
متن کاملAdsorption Isotherms on Fluoride Removal: Batch Techniques
The ability of cynodon dactylon based thermally activated carbon to remove fluoride from aqueous solution has been investigated. The batch adsorption studies were carried out at neutral pH as the functions of contact time, adsorbent dose, adsorbate concentration, temperature and effect of co-anions, which are commonly present in water. The rate of adsorption was rapid during initial 105 minutes...
متن کاملThermosensitive Chitosan Hydrogels Containing Polymeric Microspheres for Vaginal Drug Delivery
Thermosensitive hydrogels have increasingly received considerable attention for local drug delivery based on many advantages. However, burst release of drugs is becoming a critical challenge when the hydrogels are employed. Microspheres- (MS-) loaded thermosensitive hydrogels were thus fabricated to address this limitation. Employing an orthogonal design, the spray-dried operations of tenofovir...
