Transcarpathion zeolites as absorbents. Secection of the conditions of selective and sensitive determination of adsorbents with SAS(surface active substances) properties, fluorides,heavy metals,hydrozyne,hydroxylamine and sulfur containing organic substances in natural and waste wathers using the methods of chemiluminiscence,potentiometry,voltammetry and spectrophotometry investigation of the possibility of using of transcarpathion zeolites for zefinement of drinking and waste waters.Natural and waste waters are the objects under investigation.The elaborated methods were sucsessfully tested for analysis of drinking waters in varions L'viv regions, natural waters near Hrybovychi du stbin, waters of thermal power-stations,waste and natural waters of the Western Ukraine.
