摘要
分别用EDTA、中性柠檬酸铵两种萃取剂萃取并测定磷石膏中有效磷含量,通过比较,选择能够完全萃取磷石膏中有效磷的萃取剂——中性柠檬酸铵,用于磷石膏中有效磷的分析测定。
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.
