含硫物质在栲胶脱硫过程中的氧化转化
STUDY ON TANNIN EXTRACT DESULFURIZATION REACTION USING CYCLIC VOLTAMMETRY METHOD
摘要
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 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.关键词
