Abstract
Purified clinoptilolite-tuff (PCT) has successfully been tested for application in a PCT-doped wound dressing for use in radiolytically contaminated environments. Initial quantitative studies of the capacity of PCT for SrCl 2 utilizing 85 Sr radiotracered material and CsCl utilizing 134 Cs radiotracered material in both aqueous (AQ) and physiological (artificial wound fluid exudate; AWFE) media show that Cs + capacities for PCT differ slightly (AQ: 1.60 ± 0.05 mmol/g vs. AWFE: 307 1.37 ± 0.07 mmol/g) while Sr 2+ capacities are not significantly different (AQ: 0.43 ± 0.01 mmol/g vs. AWFE: 0.41 ± 0.03 mmol/g). Additionally, preliminary qualitative information relating to the selectivity of PCT for Sr 2+ and Cs + vs. Ca 2+ has been obtained from these studies. Finally, experiments show the enhanced uptake of radio-Cs and radio-Sr by PCT-doped wound dressings compared to state-of-the-art alternatives.
