material transfers physiologically essential inorganic elements in the drinking water

摘要

The invention relates to the modification of organic ion-exchangers with a view to imparting specific properties to them by introducing inorganic poorly soluble compounds into the composition thereof for the modified ion-exchangers to be used in conditioning drinking water, particularly for introducing physiologically essential macro- and microelements into drinking water. The use of the proposed material makes it possible to introduce into water not only macro- but also microelements, to stabilize the release of ions into the water, with simultaneous purification of the water from organic and inorganic admixtures. The specific output (the specific rate of water passage) with the use of such material can reach 5 min-1. The essence of the invention is that the proposed material consists of organic ion-exchangers having a porous structure in the air-dry state and inorganic poorly soluble compounds, with the with the ratio of the ion-exchanger to the poorly soluble inorganic compound being 35-90:10-65 percent by weight.
