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 ...

PH-sensitive chitosan films for baker's yeast immobilization

Oztop, HN; Saraydin, D; Cetinus, S (HUMANA PRESS INC, 2002)

Dried baker's yeast cells were immobilized on a chitosan film, which is a natural polymer. Prepared chitosan films were treated with glutaraldehyde to facilitate the immobilization of the cells. The effects of the amount ...

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) ...

Uranyl ion binding properties of poly(hydroxamic acid) hydrogels

Saraydin, D; Isikver, Y; Sahiner, N (SPRINGER-VERLAG, 2001)

Poly(hydroxamic acid) (PHA) hydrogels, obtained from the synthesis of crosslinked poly(acrylamide) (PAAm) gels have been prepared, and their uranyl ion binding properties from two different sources were investigated. ...

Adsorption of bovine serum albumin onto radiation-crosslinked poly(acrylamide/acrylic acid)

Oztop, HN; Saraydin, D; Solpan, D; Guven, O (MULTI SCIENCE PUBL CO LTD, 2004)

Poly(acrylamide/acrylic acid) (AAm/AAc) hydrogels were prepared at initial acrylic acid compositions of 70, 80 and 85 mol%, respectively. Mixtures of AAm and AAc monomers were irradiated in a Co-60 gamma-ray source at a ...

Relationship between the swelling process and the releases of water soluble agrochemicals from radiation crosslinked acrylamide/itaconic acid copolymers

Saraydin, D; Karadag, E; Guven, O (SPRINGER-VERLAG, 2000)

An attempt was made in this study to relate the releases of water soluble herbicide (sodium 2,2 dichloropropionate (Dowpon)) and model fertilizers (ammonium nitrate, potassium nitrate and ammonium sulfate) from the cylindrical ...

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 ...

Adsorption of BSA onto radiation-crosslinked poly(AAm/HPMA/MA) terpolymers

Oztop, HN; Saraydin, D; Solpan, D; Guven, O (SPRINGER-VERLAG, 2003)

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

Swelling studies of super water retainer acrylamide/crotonic acid hydrogels crosslinked by trimethylolpropane triacrylate and 1,4-butanediol dimethacrylate

Karadag, E; Saraydin, D (SPRINGER-VERLAG, 2002)

Superswelling acrylamide/crotonic acid (AAm/CA) hydrogels were prepared by free radical polymerization in aqueous solution of acrylamide (AAm) with crotonic acid (CA) as comonomer. For each copolymerization, four different ...
