This article is about Aktinum. Another extraction method is decomposed in a sodium hydroxide solution having a concentration of 45%when the temperature is 140 ° C.Metal hydroxide is extracted first and filtered at 80 ° C.It is washed in water and soaked in concentrated hydrochloric acid is dissolved.Next, the acidic solution is neutralized when it meets hydroxide (pH = 5.8).(TH (OH) 4) This material is mixed with rare earths of 2%.Most hydroxide rare earths remain in the solution.Hydroxide torium is dissolved in the inorganic acid and is separated from the rare earth element in this process.An efficient method is to soak hydroxide in nitrate and dissolve it.This is because the results of the results can be purified using organic solvents and extraction.
What is the thorium precipitate obtained by mixing acidic solutions containing thorium with hydroxide?
Hydroxy
