A CONTRIBUTION TO THE GEOCHEMISTRY OF BERYLLIUM - BERYLLIUM IN SYSTEMS WITH ORGANIC-COMPOUNDS

Experimental work was directed towards investigation the influence of selected organic compounds on the formation of soluble and insoluble s ystems (bonds) of beryllium for further conclusions about the migratio n or accumulation of beryllium in geochemical and environmental proces ses. We found that the optimal conditions of solubility of most Be-sys tems are in the pH interval 3-5, formation of insoluble hydrolytic Be( OH)(2) in the interval 5-7, non-hydrolytic insoluble compounds of Be a re formed in the pH interval 1-3. The presence of certain organic comp ounds causes specific deviations. The obtained data are applied to dif ferent natural and medicinal conditions.
