摘要： The invention concerns a method for separating trivalent lanthanide cations by selective complexing from an aqueous solution containing them. More precisely, the invention concerns a method for separating a trivalent lanthanide cation from an aqueous solution containing besides said lanthanide cation one or several other lanthanide cation(s) by contacting said solution with a specific ligand derived the all-cis-1,3,5-triamino-2,4,6-trihydroxycyclohexane (TATHC). Said solutions can be in particular aqueous solutions derived from plants reprocessing used fuel, such as solutions from fuel or aqueous effluent dissolution. They can also consist of aqueous solutions derived from rare earth, thorium and/or uranium ore treatment.

摘要： A method for treating a radioactive waste which comprises contacting a liquid waste containing a radioactive isotope with a selective adsorbent for the element of the isotope, which is soluble or easily decomposable, to thereby adsorb the isotope on the adsorbent, and then dissolving or decomposing the adsorbent. This treating method can be employed for treating a liquid waste containing an isotope with ease and with a low cost, and storing or controlling such a radioactive liquid waste with ease, which will result in reducing the load of the cost for a facility such as a tank on a medical or a research institution.

摘要： The invention relates to a method for recovering and separating metals from waste streams. Conventional processes for removing metals from waste streams include ion exchange, electrolysis and settling, which are costly, complex, cumbersome, and/or do not allow for recycling of the metal. The invention overcomes these drawbacks through a method for recovering and separating precious and non-precious metals from waste water streams, which removes, separarates, and recovers such metals in a cost effective manner with more than 95 % removal from waste streams and with minimal amounts of unprocessed solids and sludge remaining in the environment. Metals such as chromium, manganese, cobalt, nickel, copper, zinc, silver, gold, platinum, vanadium, sodium, potassium, beryllium, magnesium, calcium, barium, lead, aluminum, tin and the like are removed and recovered from the waste streams with at least 95 % removal and other metals and compounds, such as antimony, sulfur, and selenium are removed and recovered from waste streams with at least 50 % removal. The method employs a unique complexing agent comprising a carbamate compound and an alkali metal hydroxide which facilitates the formation of the metals into ionic metal particles enabling them to be readily separated, removed and recovered.

摘要： The invention concerns a method of producing a material for heavy metal absorption or for analytically detecting heavy metals, in particular uranium and radium. The method comprises the following steps: preparing a material which contains nitrogen organically bonded in a polymer; treating the material with potassium permanganate in a basic solution; and treating the material with ferrous hydroxide in a basic solution. The resultant material is suitable for use in a method of analytically detecting heavy metals and heavy metal isotopes in a sample fluid and for a method of purifying contaminated fluids.

摘要： The method has an application in the industrial productions, which produce waste solutions, with various contaminants (organic matter, sulphate ions, ammonium ions, nitrite ions, nitrate ions, arsenic, cyanide, ions of heavy metals, radioactive elements, etc.). With this method a complex purification of waste solutions independently of their qualitative and quantitative composition is realized and it is minimum to SECOND CATEGORY for waters according to the BULGARIAN STATE STANDARD (State Newpaper, No. 96 from 1986 year). The essence of the method is: the waste solutions, containing contaminants independent of their concentrations, ascendingly and gravitationally pass through the system of biobasins with the form of "turned obelisk" through the supporting layer of broken carbonate rocks, iron and a source of organic carbon situated at the bottom of the basins, intensifying the activity of the applied mixed bacterial culture, adapted in a suitable way, obtained through the combination of activated sludge from the biobasins of a purifying municipal sewage plant and sludge from the digesters of such a plant concentrated additionally with a mixed culture of anaerobic microorganisms isolated from the sludge of polluted water accepting basin.

摘要： The invention concerns a method of disposing of an organic substance, particularly an organic acid such as any of those used as complexing agents in the decomtamination of radioactively contaminated surfaces, and/or the complexes formed in a decontamination process of this kind. The method calls for permanganic acid to be mixed into a solution of the substance and any material remaining after the chemical reaction to be removed. This material may be a precipitate which is separated off by filtration, for instance, or a cation-exchange resin can be used.
