Adsorption of a Synthetic Heparinoid Polyelectrolyte on an Ion-Exchanging Surface
The adsorption of a synthetic heparinoid polyelectrolyte on poly (vinylchloride) previously treated with tridodecylmethylammonium chloride (TDMAC) was studied using radiotracer techniques to provide a more quantitative picture of antithrombogenic surface coatings. 125I-labeled polyelectrolyte was used for overall adsorption measurements. Experiments with 36Cl-labeled TDMAC yielded information o...
متن کاملHydrogels by irradiation of a synthetic heparinoid polyelectrolyte.
Gamma irradiation of aqueous solutions of a synthetic heparinoid polyelectrolyte results in the formation of hydrogels, varying in water content and mechanical strength. The equilibrium water content and the mechanical strength of the hydrogels are dependent on the initial polyelectrolyte concentration, the molecular weight of the polyelectrolyte, the percentage of double bonds in the polyelect...
متن کاملAdsorption Equilibrium and Kinetics of Lead Ion onto Synthetic Ferrihydrites
Batch experiments were conducted to study the adsorption behaviors of lead ion (Pb2+) onto ferrihydrites prepared using three different procedures which were characterized by textural analysis (BET). The adsorption removal of Pb2+ by the three ferrihydrites (called FH-1, FH-2 and FH-3, respectively) were compared, and FH-3 shows fast adsorption kinetics as well as hig...
متن کاملSimulations of Polyelectrolyte Adsorption to a Dielectric Like-Charged Surface.
We explore, using the recently developed efficient Monte Carlo simulation method, the interaction of an anionic polyelectrolyte solution with a like-charged dielectric surface. In addition to polyions, the solution also contains salt with either monovalent, divalent, or trivalent counterions. In agreement with recent experimental observations, we find that multivalent counterions can lead to st...
متن کاملPolyelectrolyte adsorption
The problem of charged polymer chains (polyelectrolytes) as they adsorb on a planar surface is addressed theoretically. We review the basic mechanisms and theory underlying polyelectrolyte adsorption on a single surface in two situations: adsorption of a single charged chain, and adsorption from a bulk solution in θ solvent conditions. The behavior of flexible and semi-rigid chains is discussed...
