Abstract
Duolite A - 101 D anyon değiştirici reçine hidroksit, klorür ve sülfat şekillerinde kobalt - 60 gama ışınları ile ışınlandı. Işınlama kuru halde ve su içinde yapıldı ve absorbe edilen doza göre radyasyonun reçine üzerindeki etkileri incelendi. Sonuçlar radyasyonun reçinenin kimyasal ve fiziksel özelliklerinde önemli değişiklikler yaptığını gösterdi.
Radyasyonla kapasite kaybı ve suya geçen bazik ürünlerin ve klorürün miktarları tayin edildi.
Reçine su içinde ışınlandığında kapasite kaybının daha yüksek olduğu görüldü.
Meydana gelen bazik ürünlerin miktarlarının primer amin, tersiyer amin, sekonder amin, amonyak sırasında arttığı bulundu.
Radyasyona karşı reçinenin sülfat halinin klorür halinden, klorür halinin de hidroksit halinden daha az stabil olduğu görüldü.
Hydroxide, chloride and sulfate forms of Duolite A - 101 D anion exchange resin have been subjected to cobalt - 60 gamma radiation in aqueous slurry or air-dried state and radiation damage has been investigated in relation to the absorbed dose. The results showed that radiation caused marked changes in the chemical and physical properties of the resin. The loss of exchange capacities have been determined and quantitative analyses of water released basic products and chloride have been made. The percentages of the loss of capacities were higher when the resin was irradiated in aqueous slurry. The yields of basic products formed were increasing in the order of primary amine, tertiary amine, secondary amine, and ammonia. The sulfate form of the resin was found to be less stable to radiation than the chloride form which in turn less stable than the hydroxide form.
