本文详细研究了铝13分离提纯的最佳工艺条件。讨论了各种影响因素。实验结果表明,聚合氯化铝(PAC)的浓度、碱度(B、OH/Al比)、Al/SO 4比、Ba/SO 4比和超声反应对Al 13的分离提纯有不同的作用。碱度在2.0左右的中等浓度的PAC对Al 13的分离有一定的好处。在此基础上,确定了制备高纯Al_(13)的最佳工艺条件:Al/SO_4:Ba/SO_4 = 1:1,超声时间为3 h。本文还讨论了Al_(13)分离的进一步指示。
The optimum process for the separation and purification of Al13was investigated in detail in this paper. The various influencing factors were discussed. The experimental results show that the concentration and basicity (B, OH/Al ratio) of polyaluminum chloride (PACl), Al/SO4ratio, Ba/SO4ratio and ultrasonic reaction have different roles in the separation and purification of Al13. Moderate concentration of PACl with the basicity around 2.0 gives some benefits in the separation of Al13. An optimization condition has then been found to obtain high purity Al13by involving Al/SO4and Ba/SO4ratios of 1:1, and 3h ultrasonic time. Further indication on the separation of Al13is also discussed.
