Abstract: | The effect of various factors on the distribution of hafnium ( 5.60 × 10?4M) between different acids and methyl isobutyl ketone (MIBK) or tributyl phosphate (TBP) was studied by using 176 + 181 Hf as a tracer, when the extraction is made from 7.5–11M hydrochloric acid with an equal volume of IM TBP in benzene, hafnium is extracted quantitatively (>99%). The hafnium can be stripped with 1–3M hydrochloric acid. |
