Description
| - Iodine was determined in foodstuffs consumed in Libya employing two modes of NAA.The first mode was instrumental using short-time irradiation with epithermal neutrons behind a Cd shield(EINAA). The other mode utilized shor-time irradiation with the reactor-pile neutrons followed by radiochemical separation (RNAA). The radiochemical separation procedure was based on the alkaline-oxidative fusion of samples and extraction of elemental iodine into chloroform. Separation yield determined using the radiotracer131 I was within the range of 90 to 95%. For guality control purposes,standard reference materials were analyzed in both modes employed.Using RNAA, a decection limit of ~1 ng g -1 could be obtained indicating superiority of the method in measuring ultra-trace levels of iodine. On the other hand, more than one order of magnitude higher detection limit did not allow sufficiently accurate determination of iodine in Libyan foodstuffs using EINAA.

- Obsah jódu v potravinách konzumovaných v Libyi byl stanovován s použitím instrumentální a radiochemické neutronové aktivační analýzy (INAA a RNAA). Postup INAA byl založen na krátkodobé aktivaci v kadmiovém stínění, tj.aktivaci epitermálními neutrony. Postup RNAA byl založen na krátkodobé aktivaci celým spektrem neutronů a následné radiochemické separaci jódu sestávající z rozkladu vzorku alkalickým oxidačním tavením a extrakce elementárního jódu do chloroformu. Pro stanovení jódu v libyjských potravinách na úrovni ng/g se ukázalo nevyhnutelné použití RNAA, neboť mez detekce jódu metodou INAA byla minimálně o řád vyšší. (cs)
