Embodiment approach
[0206] An inorganic scavenger for sulfate ions, wherein the amount of ionic impurities dissolved in pure water is 500 ppm or less and the amount of sulfate ions is 30 ppm or less, and the sulfate ion exchange capacity is preferably 10 to 0.5 meq / g.
[0207] A kind of hydrotalcite compound, it is in the inorganic scavenger of sulfate ion, and the amount of the ionic impurity that dissolves in pure water is below 500ppm and the amount of sulfate ion is below 30ppm, and sulfate ion exchange capacity is preferably 10 ~0.5meq / g.
[0208] A kind of hydrotalcite burnt product, it is in the inorganic scavenger of sulfate ion, and the amount of the ionic impurity that dissolves in pure water is 500ppm or less and the amount of sulfate ion is 30ppm or less, and sulfate ion exchange capacity is preferably It is 10~0.5meq / g.
[0209] A hydrotalcite compound or hydrotalcite fired product obtained by using a production method utilizing nitrate ion treatment, wherein the amount of ionic impur...
Embodiment 1
[0218] Dissolve 134.6g of magnesium nitrate hexahydrate and 93.8g of aluminum nitrate nonahydrate in 200ml of pure water, keep the solution at 25°C and dissolve 97.4g of sodium carbonate and 160g of sodium hydroxide in 1L of pure water To adjust to pH10.3. Then, aging was carried out at 98° C. for 24 hours. The precipitate after cooling was washed with pure water to obtain hydrotalcite compound 1 (sulfate ion inorganic scavenger A1). When analyzed for this compound, it was Mg 4.5 Al 2 (OH) 13 CO 3 3.5H 2 O.
Embodiment 2
[0220] The hydrotalcite compound 1 prepared in Example 1 was heat-treated at 550° C. for 6 hours. Then, it was pulverized to obtain a fired product of a hydrotalcite compound (sulfate ion inorganic scavenger A2). When analyzed for this compound, it was Mg 4.5 Al 2 o 7.5 .
