摘要
多硫化物溶液除了含有S2-、S22-、S32-、S42-、S52-、HS-、H2S外,还存在S2O32-、HS2O3-、H2S2O3、S4O62-、S5O62-、S2O42-、HS2O4-、S3O62-等。通过它们之间的一系列化学反应,并参考硫化钠浸出镍电解液除铜渣试验结果,通过热力学计算得出了多硫化物溶液体系中各物质的分配平衡。
As a complex system, polysulfide solution had many kinds of sulfide materials including S^2-、S2^2-、S3^2-、S4^2-、S5^2-、HS^-、H2S and S2O3^2-、HS2O3^-、H2S2O3、S4O6^2-、S5O6^2-、S2O6^2-、HS2O4^-、S3O6^2- etc. The distribution equilibrium of these materials in polysulfide system were obtained with ther modynamic calculation based on their chemical reactions and referred the leaching results of de-copper resi due slag by sodium sulfide.
