| titleOfInvention | A kind of test method of eutectic phosphorus content in phosphogypsum |
| abstract | The invention provides a method for testing the content of eutectic phosphorus in phosphogypsum. The test method comprises: mixing pretreated phosphogypsum with an inorganic acid solution, the concentration of the inorganic acid solution being 0.0001-0.01mol/L, After the reaction, solid-liquid separation is obtained to obtain a pickling solution; the obtained pickling solution is tested for phosphorus content and sulfate content; the phosphorus in the phosphogypsum is completely dissolved by an acid solution method, and the total phosphorus content of the phosphogypsum is determined; the above total The difference between phosphorus content and phosphorus content is the content of eutectic phosphorus in phosphogypsum. According to the types of phosphorus impurities in phosphogypsum, the present invention selects corresponding pickling process conditions to ensure the complete dissolution of soluble phosphorus and insoluble phosphorus in phosphogypsum, and then compares with the total phosphorus content in phosphogypsum to quantitatively obtain the total The content of crystalline phosphorus is convenient for studying the influence of eutectic phosphorus content on the properties of phosphogypsum; the method is simple to operate, simple in process, low in cost and broad in application prospect. |
