摘要
在２５ ℃Ｎａ＋ ，Ｋ＋ ∥ＮＯ－３ ， Ｃｌ－ ，ＳＯ２－４ ，Ｈ２ Ｏ相图的基础上，分析研究了新疆杂硝石矿浸取液在滩晒过程中各种盐的析出顺序及析出量，讨论了蒸发终止点及半成品中Ｋ＋ 、ＮＯ－３ 含量变化等问题。
Based on the analysis of phase diagram of Na +,K +//NO - 3,Cl -,SO 2- 4,H 2O at 25 ℃,the sequence and the quantity of various salts which salt out from the solution obtained by leaching saltpeter in the sunning process are studied.The end-point of evaporation and the change of content of K +,NO - 3 in the semi-finished product are also discussed.
