| 摘 要： | 对ＳＯ＾２－４／Ｂａ＾２＋法分离提纯Ａｌ１３形态的影响因素进行了研究，实验结果表明，聚合铝浓度、ＳＯ４／Ａｌ比、Ｂａ／ＳＯ４摩尔比、以及超声反应时间对分离效果上具有较大的影响。较高浓度的聚合铝利于沉淀的形成与分离。同时选用１：１的ＳＯ４／Ａｌ与Ｂａ＾２＋的共存对形态分析不产生影响，形态鉴定结果表明，经过上述分离条件所得产物形态为Ａｌ１３。

| Abstract: | An extensive study has been carried out on the various factors during the sepa-ration and purification of Al13 with SO4/Ba method. The experimental results show that the concentration of PACl, S04/A1 ration , Ba/SO4 ratio and time for ultrasonic reaction all exhibit significant effect on the separation efficiency. The optimum separation condition is then established. Further characterization by using 27Al NMR verifies the purified products are exactly Al13 species. |
