Abstract
Applying rapid radiochemical separation of iodine coupled with epithermal neutron activation, we reliably determined trace amounts /6–95 ng/ of iodine in rock samples such as sedimentary rocks and chondritic meteorites. Our data on meteorites are in good agreement with literature values, but for sedimentary rocks the present data were systematically lower than the literature values. Based on the data from duplicate analyses of some sedimentary rocks and the results of tracer experiments employed parallel to the rock analyses, we concluded that the analytical results obtained in this work for sedimentary rocks were more reliable than the literature values.
The PVP interaction with IB takes place by so-called dissolution of IB in the presence of humidity. This process is met in the speciality literature for the cases of other drugs too (naproxen, captopril and cetoprofen) [ 21 , 27 , 28 , 36 – 38
