钒—铜铁试剂在微酸介质中形成内络盐于—0.90V处产生吸附波已有报导,在该体系中引入硫氮蒽碱性染料次甲基蓝后,于—0.85V出现一灵敏的还原波,进一步测定络合比组成MB:V:CuP为1:1:4,又因钒(V)与钢铁试剂呈饱和匹配VO(CuP)_3,其络合比为1:3。根据电中性和匹配位饱和
It has been reported that the vanadium-copper-iron reagent forms an internal complex salt in a slightly acidic medium to generate an adsorption wave at -0.90 V. A sensitization of -0.85 V appears after introduction of the azide anthracene basic dye methine blue in the system The complexing ratio of vanadium (V) to steel reagent VO (CuP) 3 was determined by further determination of complexing ratio MB: V: CuP 1: 1: 4. Saturated based on neutrality and matching
