كاربرد جاذب هاي معدني و آلي براي آمايش پسمان هاي مايع هسته اي با سطح اكتيويته پايين

In this survey, two types of natural organic and inorganic sorbents were studied for adsorbtion features in batch and column method. Chitin and derivatives extracted from Shrimp shell waste as organic and Firuzkooh Clinoptilolite and Na form derivatives as inorganic sorbent were applied. Both are able to adsorb and decontaminate low-level radioactive liquid waste (LLW). Total Sorption was depended on PH solution, treating time, adsorbents type and particle size of sorbents and it was independent of temperature. Chitin group sorbents were more effective on Co and their sorption depend on the deacetilation factor. The best Cs adsorption was on Na from Clinoptilolite; however, Chitin derivatives were more effective than Zeolite sorbents in removal of radionuclides such as Cs, Mn, Sr and Co. Chitosan I had the best and natural Firuzkooh Clinoptilolite had the worse sorption performance in comparison with other adsorbents.
