| | The properties and the application of the vanadium phosphomolybdate-nile blue ionassociated complex were studied. Its color is blue in 2. 3N sulfuric acid. lt is more stable in the presence of polyvinyl alcohol. The constituent ratio of vanadium phosphomolybdate to nile blue is 1:4. The complex and the reagent have maximum absorption at 570 nm and 630 nm respectively. The complex has a molar absorptivity of 1. 3×10~5. Beer's law is obeyed for vanadium in the concentration of 0 to 10 μg/50 ml. In order to el... | | 本文提出了磷钼钒杂多酸与耐尔蓝形成的离子缔合物并研究了它的性质及其应用,该络合物在水相中呈蓝色,它和试剂的最大吸收峰分别为570、630nm,表观摩尔吸光系数为1.3×10~5,在0-10μgV_2O_550ml中符合比尔定律。磷钼钒杂多酸与耐尔蓝的组成比为1:4。提高酸度可以降低过剩试剂吸光度,加入磷酸可消除钛的干扰,不经任何分离可以测定岩矿中微量钒。 | | 文摘来源 | | α-Naphthoyl Nile Blue (NNB), which is a new electron-transfer mediator, was synthesized with α-naphthoic acid and Nile Blue (NB). The procedure was reported and the selection of solvents for naphtho ylization reaction was discussed. The properties of NNB were detemined by spectroscopic and electrochemical methods, and were compared with those of NB. It was found that a reversible redox process of NNB occurs in a certain potential region, two electrons and two protons taking part in the reaction. NNB modifie... | | 介绍以α-萘甲酸和耐尔蓝(NB)为原料合成?电子传递中间体α-萘甲酰耐尔蓝(NNB)的步骤,选择合适溶剂是进行酰胺化反应的关键,对新化合物进行光谱和电化学测定,比较它与NB的性质差别,NNB在一定电位区内能接近可逆地进行氧化还原,反应中有2个电子和2个质子参加;它在中性和弱碱件介质中有较好的稳定性,对NADH的电化学氧化有明显的催化作用。 | | 文摘来源 | | A new sensitive spectrophotometrie system for the determination of microamount of niobium has been developed. In the 0.025~0.1mol/L sulfuric acid solution, niobium(Ⅴ) reacts with ammonium molybdate to form a heteropoly molybdoniobic acid complex (NbMo). Then in 1.08~1.8 mol/L sulfuric acid medium, the heteropoly acid with nile-blue forms an ion-associated complex in the presence of polyvinyl alcohol. The absorption maximum of the ion-associated complex is at 615 nm and its apparent molar absorptivity is 2.4... | | 在聚乙烯醇-124存在下,耐尔蓝与铌钼杂多酸形成离子缔合物的适宜条件为:在0.025~0.10mol/L硫酸溶液中形成铌钼杂多酸;在1.1~1.8mol/L硫酸溶液中耐尔蓝与铌钼杂多酸形成离子缔合物。缔合物的组成比为NB:NbMo=3:1,λ_(maX)在615nm处,摩尔吸光系数ε为2.46×10~6L.mol~(-1).cm~(-1),符合比耳定律范围0~1.2μg Nb/25ml,至少稳定5h。考察了43种共存离子的影响,绝大多数元素不干扰测定。方法选择性好,灵敏度高,已用于合金钢和岩矿中铌的测定,结果满意。 | | 文摘来源 | |   | | << 更多相关文摘 |
