The determination method of adherent water in phosphogypsum at home and broad is analyzed, the effects of differenees drying processing methods, preserving way and time on the results of phosphogypsum adherent water determination are researched. The results show that the quick determination method, whieh using 10 g sample washed and filtered by anhydrous alcohol and dried 1 hour in (45± 2) ℃, is the most aeeurate; The samples of adherent water determination should be preserved in bottle with ground stopper, and with 3 d for a time limit.
