【摘要】：在鈦白廢酸中,鈦量約是鈧的500倍。因此,在提鈧工藝中,除鈦是關(guān)鍵,常見的方法是萃取法。實(shí)驗(yàn)研究表明,在硫酸加雙氧水除鈦方法中,當(dāng)洗液中硫酸酸度為6 mol/L,雙氧水含量為4%,洗滌溫度為70℃,攪拌時(shí)間為25分鐘,洗滌段為6級,洗滌相比O/A=3∶1時(shí),負(fù)載有機(jī)相中鈦的去除率為99.67%,且洗滌過程中鈧未損失。
[Abstract]:In titanium white waste acid, titanium content is about 500 times that of scandium. Therefore, in the process of scandium extraction, titanium removal is the key, and the common method is extraction. The experimental results show that in the method of removing titanium with H _ 2SO _ 4 and H _ 2O _ 2, the acidity of sulfuric acid is 6 mol / L, the content of hydrogen peroxide is 4, the washing temperature is 70 鈩，
