Title:
【発明の名称】重金属イオンを水溶液から分離する方法
Document Type and Number:
Japanese Patent JPS5857204
Kind Code:
B2
Abstract:
In a method of separating ionized substances such as heavy metal ions from a 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.
