Solvent extraction experiment of Sc was investigated.The extraction system consisted of 25% TBP+60% sulfonated kerosene +15% reforming agents. The results show that the extraction rates of Sc can reach up to 95%.The removing of Fe,Mn and Ti can be reached 99.1%, 99.4% and 99.5% respectively.The anti-extraction rates from organic phase with NaOH reach up to 99.7 % with effective separation from Fe,Mn and Ti.

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
