However, since the content of Fe is much higher than other impurities, if the activated carbon treatment is carried out after the crystallization of FeSO4, the load on the activated carbon will be reduced. This is preferable because it can reduce the

いる。Example 4 Take 500 sJJ of titanium sulfate solution to a beer strength of 12, and add activated carbon (Tararecol GLC) to this solution 12.5. ．． 2
5 g of each were added, and the titanium sulfate solution was brought into contact with the activated carbon for 1 to 3 hours while stirring. The results are shown in Tables 6 and 7. In this example, the amount of activated carbon was reduced compared to the column method, but impurities were separated with good selectivity.
