ABSTRACT:
In a method of separating ionized substances such as heavy metal ions from mixture dissolved in aqueous solution such as sea water, lake water, waste water and the like containing at least 0.5 mM ions by means of complex formers adapted to react and enter into a combination with the substances to be separated. The method is characterized primarily by adding to the aqueous solution bubbles formed by cells of living organisms the content of which has an osmolarity differing within limitation from osmolarity of the aqueous solution. The complex formers for purposes of being received through the cells are added to a solution the osmolarity of which is lower than the cell content of the cells. The addition of the complex formers to the complex former receiving solution is contained until due to the osmosis through the cell skin acting as diaphragm, in the state of equibrium between the solution in the interior of the cells and the solution containing the complex formers, the cell content practically corresponds to the solution containing the complex formers.
The osmolarity of the solution containing the complex formers is increased by adding osmotically active substances selected from the group consisting of calcium ions, potassium ions, sodium ions to the osmolarity which corresponds to the osmolarity of the cell content of the originally introduced cells. Subsequently thereto the bubbles formed by the exchange of the cell content of the cells and containing the complex formers are separated from the solution containing the complex. Thereafter the thus separated bubbles are introduced into the aqueous solution until the substance to be separated from the aqueous solution and to be ionized have moved into the interior of the bubbles through the skin of the bubbles and by the complex formers have been converted into complexes which are difficult to be disassociated or dissolved whereupon the cells are separated from the aqueous solution.
