| 成果简介 | NOVELTY - Invention relates to agriculture and can be used in production of sulphur-containing fertilizers. Method of producing a fertilizer composition based on calcium polysulphide involves reacting elemental sulphur with an aqueous solution of calcium hydroxide to obtain an aqueous solution of calcium polysulphide and a waste in form of a suspension containing calcium hydroxide and elemental sulphur. Further, an aqueous solution of calcium polysulphide is separated and 50% aqueous solution of nitric acid is added to the obtained waste in the form of a suspension until pH=7 with formation of calcium nitrate and a precipitate of elemental sulphur. Precipitate of elemental sulphur is separated by filtration, dried and reused when producing calcium polysulphide. Aqueous solution of calcium nitrate is added to an aqueous solution of calcium polysulphide to form a fertilizer composition. USE - Agriculture. ADVANTAGE - Disclosed method of producing a fertilizer composition based on calcium polysulphide provides solving environmental problems in the production of calcium polysulphide, reducing the cost of production due to the absence of wastes. 1 cl, 1 dwg, 1 ex |
