TAILIEUCHUNG - A method for properties evaluation of activated charcoal sorbents in iodine capture under dynamic conditions

The sorption capacity index a is proposed as a criterion parameter for assessing the quality of impregnated activated charcoals. It was found that this parameter does not depend on the dynamic conditions during the sorbent test. It was shown that values of the sorption capacity index allow to recommend iodine sorbents for industrial gas cleaning processes. | A method for properties evaluation of activated charcoal sorbents in iodine capture under dynamic conditions Nuclear Engineering and Technology 51 (2019) 641e645 Contents lists available at ScienceDirect Nuclear Engineering and Technology journal homepage: Technical Note A method for properties evaluation of activated charcoal sorbents in iodine capture under dynamic conditions Eldar P.
