| 摘 要： | 采用循环伏安法考察了H2S气体吸收转化生成的含硫物质HS-和Sx2-在五价钒V(V)和氧化栲胶以及两者共同作用下的氧化转化过程.结果表明,反应过程可分为初始快速反应阶段和稳定慢速反应阶段.在各反应中,含硫物质和五价钒V(V)的反应速率比其和氧化栲胶的反应速率快;另外,氧化栲胶有助于S26-的生成,五价钒V(V)能够促进含硫物质向单质硫转化.

| Abstract: | Reaction H2S absorption solution and pentavalent vanadium,tannic extract with oxidization state(Teos) was investgated using cyclic voltammetry method.The results show that H2S is absorbed to produce bisulfide ion HS-and polysufide ion S2-x,then these sufur-containing substances will be oxidized by pentavalent vanadium and Teos.The reaction can be divided into initial rapid reaction stage and slow reaction stage.For different reactions,reaction rate of sufur-containing substance and pentavalent vanadium is faster than that of sufur-containing substance and Teos.Additionally,Teos contributes to the formation of S2-6,and pentavalent vanadium can promote to the transformation from sulfur containing substance to elemental sulfur. |
