| 摘 要： | 采用阴离子交换分离，磷钼蓝比色法测定三聚磷酸钠溶液水解后各组分含量。经研究表明，在中性水中，三聚磷酸钠水解成正磷酸盐和焦磷酸盐。随着时间长，三 聚磷钠水解程度加大；在放置６０多天后，水解物组成趋于稳定。

| Abstract: | By using molylebdum-blues colormetric determination and anion exchange resin separation of sodium tripolyphoshate aqueous solution,it is proved that sodium tripolyphoshate in neutral water,changes into stable orthophoshate and pyrophosphate in varying degrees.With time going,hydrolysis degree increases.After more than 60 days,the composition of hydrolysate is nearly stabilizing. \ \ |
