摘要
The optimum process for the separation and purification of Al-13 was 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/SO4 ratio, Ba/SO4] ratio and ultrasonic reaction have different roles in the separation and purification of Al-13.Moderate concentration of PACl with the basicity around 2.0 gives some benefits in the separation of Al-13. An optimization condition has then been found to obtain high purity Al-13 by involving Al/SPO4 and Ba/SO4 ratios of 1:1, and 3h ultrasonic time. Further indication on the separation of Al-13 is also discussed. (C) 2003 Elsevier B.V. All rights reserved.
