Abstract
Sposób otrzymywania siarczanowych roztworów cyrkonu(IV) i hafnu(IV) z ich roztworów szczawianowych metodą strąceniową charakteryzuje się tym, że cyrkon i hafn z roztworów szczawianowych strąca się jako Zr(Hf)O2•xH2O za pomocą nadmiaru stężonego NH3aq, korzystnie w stosunku molowym NH3:Zr(Hf) = 80-100, na gorąco, korzystnie w temperaturze 80 do 90°C, po czym sączy się i dokładnie przemywa wodą, a następnie roztwarza w st. (95%) H2SO4, korzystnie w stosunku molowym H2SO4: Zr(Hf) = 7-9.The method of obtaining sulfate solutions of zirconium (IV) and hafnium (IV) from their oxalate solutions by precipitation method is characterized in that zirconium and hafnium from oxalate solutions are precipitated as Zr (Hf) O2 • xH2O with an excess of concentrated NH3aq, preferably in molar ratio NH3: Zr (Hf) = 80-100, hot, preferably at 80 to 90 ° C, after which it is filtered and thoroughly washed with water, and then reconstituted at 95 () with H2SO4, preferably in H2SO4 molar ratio: Zr (Hf) = 7-9.
