In vitro dynamic swelling behaviors of radiation synthesized polyacrylamide with crosslinkers in the simulated physiological body fluids

Saraydin, D; Isikver, Y; Karadag, E; Sahiner, N; Guven, O (ELSEVIER SCIENCE BV, 2002)

Acrylamide hydrogels, containing different amounts and types of crosslinkers, were synthesized via gamma-irradiation technique. Their swellings in simulated body fluids, such as physiological saline (0.89% NaCl) isoosmotic ...

Radiation induced acrylamide/citric acid hydrogels and their swelling behaviors

Karadag, E; Saraydin, D; Sahiner, N; Guven, O (MARCEL DEKKER INC, 2001)

Citric acid (CAc) moieties containing acrylamide (AAm) hydrogels were prepared by gamma irradiation of their aqueous solutions. A possible polymerization and crosslinking mechanism for acrylamide/citric acid (AAm/CAc) ...

Swelling of superabsorbent acrylamide/sodium acrylate hydrogels prepared using multifunctional crosslinkers

Karadag, E; Saraydin, D (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2002)

Superwaterabsorbent acrylamide-sodium acrylate hydrogels were prepared by free radical polymerization in aqueous solutions of acrylamide and of acrylamide with sodium acrylate as comonomer. For each copolymerization, nine ...

Dynamic swelling behavior of gamma-radiation induced polyelectrolyte poly(AAm-co-CA) hydrogels in urea solutions

Karadag, E; Uzum, OB; Saraydin, D; Guven, O (ELSEVIER SCIENCE BV, 2005)

The aim of this study was to investigate the equilibrium swelling properties in urea solutions of gamma-radiation induced polyelectrolyte copolymeric hydrogels consisting of acrylamide (AAm) and crotonic acid (CA). ...

Radiation crosslinked poly(acrylamide/2-hydroxypropyl methacrylate/maleic acid) and their usability in the uptake of uranium

Saraydin, D; Solpan, D; Isikver, Y; Ekici, S; Guven, O (MARCEL DEKKER INC, 2002)

The terpolymeric poly(acrylamide/2-hydroxy propylmethacrylate/maleic acid) (AAm/HPMA/MA) hydrogels in the rod form have been prepared by gamma radiation of quaternary mixtures of acrylamide/2-hydroxy propylmethacrylate/ ...

Synthesis, characterization and evaluation of IPN hydrogels for antibiotic release

Ekici, S; Saraydin, D (TAYLOR & FRANCIS INC, 2004)

We prepared new ternary interpenetrating polymeric networks (IPN) systems containing chitosan, poly(N-vinylpyrrolidone) and poly(acrylamide) polymers. IPNs were synthesized by radical polymerization of acrylamide monomers ...

Nicotine-selective radiation-induced poly(acrylamide/maleic acid) hydrogels

Saraydin, D; Karadag, E; Caldiran, Y; Guven, O (PERGAMON-ELSEVIER SCIENCE LTD, 2001)

Nicotine-selective poly(acrylamide/maleic acid) (AAm/MA) hydrogels prepared by gamma -irradiation were used in experiments on swelling, diffusion, and interactions of the pharmaceuticals nicotine, nicotinic acid, nicotinamide. ...

Use of superswelling acrylamide/maleic acid hydrogels for monovalent cationic dye adsorption

Saraydin, D; Karadag, E; Guven, O (JOHN WILEY & SONS INC, 2001)

Acrylamide/maleic acid (AAm/MA) superswelling hydrogels prepared by irradiation with gamma radiation were used in experiments on swelling, diffusion, and adsorption of some water-soluble monovalent cationic dyes such as ...

Polyelectrolyte CASA hydrogels for uptake of uranyl ions from aqueous solutions

Karadag, Erdener; Uzum, Omer Baris; Kundakci, Semiha; Saraydin, Dursun (JOHN WILEY & SONS INC, 2007)
