چکیده

اثر پرتو گاما بر ظرفیت تبادل یون کلینوپتیلولیت سدیمی بررسی شد. پرتودهی نمونه‌ی‌ جاذب با تابش گاما با دز جذب شده‌ی 70 کیلوگری تا 2 مگاگری انجام و ظرفیت جذب کروم (VI) بر روی آن، تحت شرایط مختلف و با استفاده از طیف‌سنجی جذب اتمی اندازه‌گیری شد. جذب کروم (VI) در گستره‌ی غلظتی 80 تا ppm 1800 و در pH برابر 7 انجام شد. نتایج نشان داد که تابش گاما تا دز 2 مگاگری تأثیری بر ظرفیت جذب کروم (VI) به وسیله‌ی شکل سدیمی کلینوپتیلولیت ندارد.

چکیده [English]

Abstract: The influence of gamma ray radiation on ion-exchange capacity of sodium-clinoptilolite was studied. The absorber sample was subjected to gamma irradiation with doses of 70 to 2000 kGy. The chromium (VI) adsorption capacity of the irradiated sample was determined by the atomic adsorption spectrometry technique. The chromium (VI) adsorption was performed in the concentration range of 80 up to 1800 PPm and with a pH of 7. The results showed that the maximal radiation dose used in this research (2000 kGy) did not affect the adsorption capacity of the studied sample.
