    摘要： Granulated lignite (brown coal) is used to provide an adsorption matrix with which sea water is brought into contact long enough to reach a substantially maximum adsorption of uranium, after which the adsorption matrix is removed from the solution and is burned with utilization of its heating value while the heavy metals are concentrated in the combustion residue, after which the thus concentrated heavy metals are recovered in the form of their salts by previously known treatment. An average grain diameter of the granular lignite between 0.5 and 2 mm is used and about 3 mg of uranium per kg of dry lignite is adsorbed with a contact time in the region between one and sixty seconds. Uranium adsorption falls off when there is a substantially greater concentration of foreign ions, particularly calcium, magnesium and sulphate.

    摘要： 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.

    摘要： Uranium or thorium cations are removed from aqueous suspension or solution by treatment of the aqueous material with the biomass derived from fermentation of a fungal microorganism of the genus Rhizopus, e.g. Rhizopus arrhizus. The process can be utilized to treat aqueous tailings from uranium ore extraction processes, to reduce the radioactive content of the tailings prior to disposal.

    摘要： A method of producing a matrix of micro-organisms for extracting and gaining uranium from sea water, according to which the matrix is made of micro-organisms occurring in nature that are exposed to x-ray irradiations. These predetermined micro-organisms accordingly form colonies or threads and are filtered easily and cultivated. These micro-organisms accordingly form colonies or threads and are filtered easily and cultivated. These micro-organisms have a ratio of surface to volume that is relatively high. Subsequently, the thus irradiated micro-organisms are placed on a nutrient medium rich in uranium and are left there until colonies are formed. Thereupon, the surviving colonies of mutants are inoculated in a nutrient solution, and are then cultivated to produce the matrix.
