摘要:
锡酸钠工艺生产过程中，因长期累积，造成母液中含砷量严重富集，致使在母液循环使用中造成产品中含砷量超标。文章采用纳米MnO2 对二次结晶后锡酸钠母液进行吸附，降低母液中含砷量，以达到循环使用。重点讨论母液与吸附剂的液固比、温度、时间、OH-浓度等因素对降低母液中含砷量的影响。结果表明，纳米MnO2对降低母液中含砷量取得良好的效果。
Abstract:
During the producing process of tin sodium, serious arsenic enrichment occurred in the mother liquor due to thelong-term accumulation, resulting in excessive arsenic products during the circulation use of the mother liquor. In this paper, the sodiumstannate after secondary crystallization was absorbed by using nano-MnO2 in the mother liquor, which reduced the arsenic content of themother liquor and could be used for recycling. This paper mainly deals with the factors of liquid-solid ratio of mother liquor with theadsorbent, temperature, time and OH- concentration to reduce the arsenic content in the mother liquor. It has been shown that thenano-MnO2 is of great effect for reducing the amount of arsenic in mother liquor.
