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 S2x- then these sufur containing substances will be oxidized by pentavalent vanadium and Teos. The reaction can be di vided 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-contai ning substance and Teos. Additionally, Teos contributes to the formation of S26- , and pentava lent vanadium can promote to the transformation from sulfur containing substance to elemental sulfur.%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S2x-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S2-6的生成,五价钒V(V)能够促进含硫物质向单质硫转化.
