the kinetic parameters of drug compounds adsorption onto mesoporous materials

چکیده
the discovery of mesoporous molecular sieves, mcm-41, which possesses a regular hexagonalarray of uniform pore openings, aroused a worldwide resurgence in this field. this is not onlybecause it has brought about a series of novel mesoporous materials with various compositionswhich may find applications in catalysis, adsorption, and guest-host chemistry, but also it hasopened a new avenue for creating of the zeotype materials. this paper presents a comprehensiveoverview of recent advances in the field of mcm-41. adsorption of drug molecules such aspseudeoephedrine hydrochloride onto mesoporous molecular sieves (mcm-41) from aqueoussolution has been investigated systematically using batch experiments in this study. resultsindicate that pseudeoephedrine hydrochloride adsorption is initially rapid and the adsorptionprocess reaches a steady state after 2 min. the adsorption isotherms are well described by thelangmuir model. based on the results, it suggests that the adsorption is primarily brought about byhydrophobic interaction between drug molecules and mcm-41 surface.

متن کاملMethodology for the immobilization of enzymes onto mesoporous materials.
Cytochrome c and xylanase were adsorbed onto two mesoporous materials, SBA-15 (a pure silicate) and MSE (an organosilicate), with very similar physical properties but differing chemical compositions. A methodical order was developed whereby the influences of surface area, pore size, extent of order, particle size, surface potentials, isoelectric points, pH, and ionic strength on immobilization ...
متن کاملKinetic aspects of the adsorption of xyloglucan onto cellulose nanocrystals.
In this work, the adsorption of a neutral flexible polysaccharide, xyloglucan (XG), onto thin cellulose nanocrystal (CNC) surfaces has been investigated to get more insight into the CNC-XG association. Gold-coated quartz crystals were spin-coated with one layer of CNC, and XG adsorption was monitored in situ using a quartz crystal microbalance with dissipation (QCM-D). The adsorption of XG unde...

The adsorption behavior of p-aminobenzoic acid and o-aminobenzoic acid onto the different polymeric adsorbents was systematically investigated as a function of the solution concentration and temperature. Experimental results indicated that the equilibrium adsorption data of the four polymeric adsorbents fitted well in the Freundlich isotherm. The adsorption capacity of multi-functional polymeri...
متن کاملAdsorption of Heavy Metal onto the Materials Prepared by Biomass
The amount of heavy metal ions released into the environment has been increased due to industrial activities and technological development. Furthermore, indiscriminate disposal has caused worldwide concern for many years because of the toxicity, accumulation in the food chain, persistence in nature, and concentration by organisms [1–3]. Heavy metals are not biodegradable and tend to accumulate ...
متن کاملAdsorption of Metallic Ions onto Chitosan: Equilibrium and Kinetic Studies
Equilibrium isotherms and the adsorption kinetics of heavy metals onto chitosan were studied experimentally. Chitosan, a biopolymer produced from crustacean shells, has applications in various areas, particularly in drinking water and wastewater treatment due to its ability to remove metallic ions from solutions. The adsorption capacity of chitosan depends on a number of parameters: deacetylati...
