Modification of cellophane membranes by -radiation: Effect of irradiation doses on electrochemical parameters
نویسندگان
چکیده
Modification caused in cellophane matrix (a highly hydrophilic natural polymer) by -irradiation was studied by determining changes in different electrochemical parameters obtained from measurements carried out with the membranes in contact with NaCl and MgCl2 solutions. Three different irradiation doses (10 Gy, 30 Gy and 80 Gy) were used in order to consider its possible effect in membrane modification. Changes in salt permeability, electrical resistance and permselectivity show modifications in the membrane matrix, which seem to produce: (i) a ( a m ©

Modification of cellulosic membranes by -radiation: Effect on electrochemical parameters and protein adsorption
This work is focused on the study of possible changes in the electrochemical transport parameters of cellulose membranes due to the effect of ionising radiation. A cellophane membrane (membrane C5) was irradiated with a dose of 80 Gy (membrane Ir80) and differences in the electrochemical parameters for pristine and irradiated samples are studied. Salt permeability, ion transport number, permsel...

TThis study investigated the water absorption of chitosan, collagen, and chitosan/collagen blend membranes exposed to gamma-ray irradiation. These membranes were produced via the solvent evaporation method. All membranes then underwent irradiation at 15 or 25 kGy gamma-ray doses, while membranes without irradiation were used as controls. After immersing the membranes in distilled water for up t...
متن کاملModification of cellulose based membranes by -radiation: Effect of cellulose content
Electrochemical characterization of three cellophane membranes with different content of regenerated cellulose was carried out by determining salt diffusion and ion transport numbers, which were obtained from diffusion and membrane potential measurements carried out with the membranes in contact with NaCl solutions at different concentrations. Results show a decrease for salt permeability with ...

Background and objective: irradiation is a physical treatment in which products are exposed to ionized radiation such as gamma and x rays to improve the security and quality. Hydrocolloids are components that are used in food science to improve texture properties. Exposing to irradiation treatment may change structural and functional properties. By regard to the importance of irradiation on dec...
متن کاملProtective Effect of Low Dose Melatonin on Radiation-Induced Damage to Rat Liver
Background: Melatonin is a free radical scavenger. It has also antioxidant effects through its stimulatory actions on antioxidant system. Objective: We conducted this study to examine the effect of different oral doses of melatonin on liver tissue. Methods: We used 42 rats—6 rats in each group. Group I served as the control group; group II rats were pretreated with only melatonin; group III w...
