Abstract： During the producing process of tin sodium, serious arsenic enrichment occured in the mother liquor due to the long-term accumulation, resulting in excessive arsenic products during the circulation use of the mother liquor. In this paper, the stannate after secondary crystallization was absorbed by using nano-MnO2 in the mother liquor, which reduced the arsenic content of the mother liquor and could be used for recycling. This paper mainly deals with the factors of liquid-solid ratio of mother liquor with the adsorbent, temperature, time and OH-concentration to reduce the arsenic content in the mother liquor. It has been shown that the nano-MnO2 is of great effect for reducing the amount of arsenic in mother liquor. 供参考。 |
