Adsorption of some basic dyes by acrylamide-maleic acid hydrogels
(MARCEL DEKKER INC, 1996)
In this study, acrylamide-maleic acid (AAm/MA) hydrogels containing different quantities of maleic acid have been irradiated with gamma-radiation. They have been used in experiments on swelling, diffusion, and the adsorption ...
Cationic dye adsorption by acrylamide itaconic acid hydrogels in aqueous solutions
(JOHN WILEY & SONS LTD, 1997)
Acrylamide/itaconic acid (AAm/IA) hydrogels containing different quantifies of itaconic acid have been irradiated with gamma radiation. The hydrogels were used in an experiment concerning the adsorption of cationic dyes ...
Influence of some crosslinkers on the swelling of acrylamide crotonic acid hydrogels
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 1997)
Acrylamide-crotonic acid hydrogels in the form of rods are prepared by gamma-irradiation of quaternary mixtures of acrylamide-crotonic acid-crosslinker-water with 2.6 and 5.2 kGy gamma-rays. The influence of the applied ...
In vitro dynamic swelling behaviors of radiation synthesized polyacrylamide with crosslinkers in the simulated physiological body fluids
(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
(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
(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
(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)
(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
(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 ...
Adsorption of some anionic azo dyes onto crosslinked poly(N-vinylpyrrolidone) from aqueous solutions
(EDITURA ACAD ROMANE, 1998)
In this study, bindings of anionic azo dyes containing sulphonyl group such as acid red 26, acid red 103, direct yellow 9, acid black 1 and acid orange 52 onto crosslinked poly(N-vinylpyrrolidone) (CPVP) have been investigated. ...
