Abstract: | The effect of hydrophobization of Ag-containing nonmodified and acetylene-modified zeolites with poly(vinyl chloride) (PVC) on sorption characteristics of sorbents with respect to CH3
131I was studied. The PVC coating on the sorbent results in increased absorbtion of CH3
131I from a water vapor-air flow at a humidity of up to approximately 70 vol %; the decontamination factor of approximately 105 is reached. The sorbent modified with PVC retains radioiodine at heating to 300°C and can be proposed for practical purposes. |
