| Abstract: | By means of EDTA, neutral ammonium citrate as two kinds of extracts the effective phosphorus content in phosphogypsum is determined. Through comparison, neutral ammonium citrate was choiced as extraction agent because it can complete extract the effective phosphorus in phosphorus gypsum and can be used for determination the effective phosphorus in phosphorus gypsum. |
