Kinetics of Adsorption of Linear Homopolymers onto Flat Surfaces: Rouse Dynamics

چکیده
The dynamic properties o< unentangled adsorbed polymer layers are considered theoretically. The kinetics of penetration of a chain in an adsorbed layer is considered as a twostep process: entry corresponding to the attachment of the chain on the adsorbing surface and spreading on the surface. We discuss three types of experiments, the formation of an adsorbed layer, the desorption from an adsorbed layer and the exchange between an adsorbed layer and a bulk solution. The bottleneck for the adsorption of a new chain onto a solid wall (already covered by polymers) is the spreading stage corresponding to creation of G contacts with the wall with a

The Study of Adsorption Characteristics of 1-Chloro-4-Nitrobenzene onto Multi-Walled Carbon Nanotubes Surfaces from Aqueous Solution: Equilibrium and Kinetics
In this study adsorption of 1-chloro-4-nitrobenzene (CNB) from aqueous solutions onto multi-walled carbon nanotubes (MWCNTs) was surveyed. The effect of some key parameters such as pH (2-10), carbon nanotubes dosage (0.02-0.1 mg/250mL), CNB concentration (2- 16 mg/L), and temperature (20,30,40,50°C) were investigated. The results showed that, the variation of initial pH and CNB concentration ex...

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 کاملAdsorption of semiflexible block copolymers on homogeneous surfaces.
We present the results of extensive numerical off-lattice Monte Carlo simulations of semiflexible block-copolymer chains adsorbed onto flat homogeneous surfaces. We have compared the behavior of several chain structures, such as homopolymers, diblocks, (A(alpha)B(alpha)) block copolymers, and random heteropolymers. In all the cases studied, we have found the adsorption process to be favored wit...
متن کاملInvestigation of effective parameters on adsorption of amoxicillin from aqueous medium onto activated carbon
In this study, the adsorption of amoxicillin onto activated carbon was investigated. The effect of particle size and the effluent flow rate was discussed as well as the kinetics and isotherm of adsorption equilibrium. The isotherm equilibrium studies showed that the Langmuir model was appropriate for describing the adsorption equilibrium of amoxicillin onto the activated carbon. Furthermore, th...
