TRACE ELEMENT COMPOSITION OF AQUEOUS EXTRACTS OF SOME DIATOMITE AND LYDITE SAMPLES FROM KARELIA
The relevance of the research consists in the necessity to obtain reliable information on microelemental composition of aqueous extracts of diatomite and lydite. Currently, diatomites are expected to be widely used in medical, pharmaceutical and food industries, but a detailed study of their composi...
