摘要
介绍了以Na2S-NaOH作浸出剂,在强碱性介质中浸出锑砷烟灰中锑和砷,然后继续保持碱性条件,用氧化剂氧化浸出液,使锑、砷分离,分别制取焦锑酸钠NaSb(OH)6和砷酸钠Na3AsO4;而烟灰中的其它金属离子富集于浸出渣中得以回收。
Using Na2S- NaOH as leaching agent, in the present of strong base medium , Sb and As were separated from ash, then sodium pyroantimonate and sodium arsenate were prepared. Other metal ions were also recovered from ash.
