|
The active transport characteristics of anions of cell membrane model which irradiated by ??Co γ-ray was investigated. The cell membrane model used in this experiment was a sulfonated copolymerized membrane of poly(1-methyl-4-vinylpyridiniumiodide-co-divinylbenzene : MeVP-DVBI). First, the initial flux of OH? and Cl?, Na? of membrane which was not irradiated was decreased with increase of thickness of membrane 80-200㎛, increased with increase of NaOH concentration 0-0.5mol/L and MeVP-DVBI concentration 20-80% was increased with initial flux of OH? and Cl?, decreased with initial flux of Na?. Second, the initial flux of membrane which was irradiated was less than that. And the driving force of pH of irradiated membrane was significantly increased more than membrane which was not irradiated. The initial flux of the OH? ion was decreased with increase of H? ion concentration. As selective transport of OH? and Cl? of cell membrane model were abnormal, cell damages were appeared at cell.
