Different forms of Transcarpathian clinoptilolite were used for preparation of water samples to the analysis. It was shown the using possibility of these adsorbents as filters for waters purification and also for utilization of rare and noble metals (Pd, Tb and Ag). The highly sensitive method of the Tb luminescent determination in the presence of different REE after previous concentration in the mode of solid face extraction on Transcarpathian clinoptilolite has been elaborated. The highly sensitive selective methods of direct chemiluminescent, voltammetric and kinetic determination of thioglycolic acid, sulphites, Со, Ni and Fe in waters and biosubstrata have been elaborated. The devised methods are applied in the State enterprise engineering centre "Techno-resource" of NAS of Ukraine (Lviv) and they are approved on natural and waste waters of western region of Ukraine as well as on biosubstrata (blood plasma, saliva). The results obtained are published in 44 scinentific papers and 46 reports on scientific conference. The results were also included into three candidate theses.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
