Claims (11)

1. Способ удаления N-(фосфонометилглицина) (глифосата) или его соли или его ионной формы из водной смеси, в которой он находится, когда эта водная смесь представляет собой жидкие отходы промышленного производства глифосата, который предусматривает введение в смесь ионов, способных к образованию нерастворимых или частично растворимых комплексных солей глифосата, и выделение комплексных солей из смеси.1. The method of removing N- (phosphonomethylglycine) (glyphosate) or its salt or its ionic form from the aqueous mixture in which it is located when this aqueous mixture is a liquid industrial waste glyphosate, which involves the introduction of ions capable of forming insoluble or partially soluble complex glyphosate salts, and the separation of complex salts from the mixture. 2. Способ по п. 1, где ионами являются ионы кальция, магния, алюминия или железа (III). 2. The method according to p. 1, where the ions are ions of calcium, magnesium, aluminum or iron (III). 3. Способ по п. 2, в котором ионы являются ионами железа (III) и рН глифосат-содержащей смеси доводят до 6 или менее перед введением соли железа (III). 3. The method of claim 2, wherein the ions are iron (III) ions and the pH of the glyphosate-containing mixture is adjusted to 6 or less before the introduction of the iron (III) salt. 4. Способ по п.3, где рН смеси доводят до интервала значений 1-4, например, до 3. 4. The method according to claim 3, where the pH of the mixture is adjusted to a range of 1-4, for example, to 3. 5. Способ по любому из пп. 1-4, где ионы вводят в виде соли, растворимой в водном растворе при рН глифосат-содержащей смеси. 5. The method according to any one of paragraphs. 1-4, where the ions are introduced in the form of a salt, soluble in an aqueous solution at a pH of glyphosate-containing mixture. 6. Способ по п.5, где ион представляет собой железо (III) и растворимые соли представляют собой сульфат, хлорид или гидроксид. 6. The method according to claim 5, where the ion is iron (III) and soluble salts are sulfate, chloride or hydroxide. 7. Способ по п. 1 или 2, где осадок удаляют путем фильтрования или центрифугирования. 7. The method according to p. 1 or 2, where the precipitate is removed by filtration or centrifugation. 8. Способ по любому из пунктов от 2 до 7, где ионами, способными к образованию нерастворимой или частично растворимой комплексной соли глифосата, являются ионы железа (III), дополнительно включающий выделение глифосата из осадка комплексной соли путем образования осадка в виде водного шлама, имеющего рН более 8, и удаления гидроксида железа (III) или гидратированного оксида железа (III) из шлама с получением водного раствора, содержащего глифосат. 8. The method according to any one of paragraphs 2 to 7, wherein the ions capable of forming an insoluble or partially soluble complex glyphosate salt are iron (III) ions, further comprising separating glyphosate from the precipitate of the complex salt by forming a precipitate in the form of an aqueous slurry having a pH of more than 8, and removing iron (III) hydroxide or hydrated iron (III) oxide from the sludge to give an aqueous solution containing glyphosate. 9. Способ по пп. 8, где рН шлама составляет величину более 12. 9. The method according to PP. 8, where the pH of the sludge is greater than 12. 10. Способ по п. 8 или 9, где шлам получают путем добавления воды к осадку и последующего добавления основания или путем добавления осадка к водному раствору основания. 10. The method according to p. 8 or 9, where the sludge is obtained by adding water to the precipitate and then adding a base or by adding a precipitate to an aqueous solution of the base. 11. Способ по п. 10, где основанием является гидроксид щелочного металла. 11. The method according to p. 10, where the base is an alkali metal hydroxide.
