    摘要： This invention relates to a buffered phosphorus containing solution comprising at least one phosphorus compound selected from the group consisting of phosphorous acid, hypophosphorous acid, polyphosphorous acid polyhypophosphorous acid, and salts thereof. The solution also contains a buffer including an organic base in the form of a nitrogen containing compound and its conjugate acid. The solution may be used as a fertilizer or as a fungicide. The invention also relates to a method of preparing such a solution.

    摘要： The invention provides a method of reducing the sodium content of a water containing dissolved sodium ions, particularly a water with a sodium ion content of at least 100 ppm. Examples of such waters are effluents such as acid mine drainage and river waters. The method includes the steps of: (i) removing sodium, calcium and magnesium ions from the water by contacting the water with a cation exchange resin/s to capture sodium, calcium and magnesium ions thereon, (ii) treating the cation exchange resin/s of step (i) with nitric acid to produce an eluant containing sodium ions, calcium ions, magnesium ions nitrate ions and nitric acid, (iii) adding a carbonate to the eluant to precipitate the calcium and magnesium ions as calcium and magnesium carbonates; (iv) separating the precipitated carbonates from the eluant; and (v) treating the eluant from step (iv) to obtain a sodium and/or potassium nitrate product.
