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 ...
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) ...
Super water-retainer hydrogels: Crosslinked acrylamide/succinic acid copolymers
(SOC POLYMER SCIENCE JAPAN, 1997)
Super water-retainer hydrogels in the rod form were prepared by copolymerization of acrylamide and succinic acid monomers with gamma radiation. Swelling took place in water at 25 degrees C and was followed by weighing. The ...
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. ...
Swelling of superabsorbent acrylamide/sodium acrylate hydrogels prepared using multifunctional crosslinkers
(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 ...
Interaction of some cationic dyes with acrylamide/itaconic acid hydrogels
(JOHN WILEY & SONS INC, 1996)
Acrylamide/itaconic acid (AAm/IA) hydrogels prepared by irradiating with gamma radiation were used in experiments on uptake of some cationic dyes such as union green B (UG-B), basic blue 17 (BB-17), basic red 2 (BR-2), and ...
