In a supporting electrolyte containing 1.2×10~(-3)M 8-hydroxyquinoline(oxine), 0.01M KCIO_3, at PH 2.7, two sensitive reduction peaks of Molybdenum-oxine adsorption complex onto the hanging drop electrode have been obtaincd by 2.5th order differential neopolarography, preceded by a period of 1 or 2 min of stirred (or stationary) collection at an adsorption potential of -0.25V (vs SCE), using reductive potential scan (v=100mv/s). The peak potentials are located at -0.59V and -0.64V, respectively. Both peaks shift in negative direetion with increasing PH. The peak height-molybdenum concentration relationship is linear in the range from 0.4 to 24ng/ml, the regression coefficient is over 0.994. The experiment verified that the ions of Mo(Ⅵ) and Mo(Ⅴ) are all electroactive malefials, and the adsorption of oxine is less than of molyb-denum-oxide complex in this system. The results show theft the reduction wave of the adsorption complex in the presenoe of KCIO_3 is a parallel-catalysis wave with adsorptive property.

本文对Mo(Ⅵ)-Oxine-KClO_3体系Mo(Ⅵ)与Oxine配合物在悬汞电极(HMDE)上的吸附特性、催化机理和体系中的电活性物质,籍助2.5次微分新极谱法进行研究。发现该体系中,PH2.7、Eads-0.25V(对SCE)时,钼配合物能够很好地被吸附;搅拌(或静止)富集1~2分钟,阴极扫描,产生两个灵敏的还原峰,峰电位分别为-0.59V和-0.64V。二者均与钼浓度0.4~24ng/ml范围呈良好的线性关系。实验证实,Mo(Ⅵ)和Mo(V)均具有电活性,Oxine在HMDE表面有明显吸附,而钼的配合物吸附较强,其还原过程分两步进行,是一种具有吸附性质的平行催化波。

The calibration graph was linear over the range of 2. 5X 10~9 to 8X 10~8g/mL. The blank, mechanism of the reactions, interference of other ions and some optimum conditions of the method were studied in detail. The main source of the blank resulted from methylene blue and the complex of F~- methylene blue . In order to reduce the blank ,the amounts of methylene blue, H2SO4 and HF were used as less as possible. Only one to one complex BFr -methylene blue was formed in the medium of H2SO,|. About 90% of methylene blue and F~-methylene blue complex was removed with 5mL of water and only a little amount of BFr-methylene blue complex was decomposed. The extraction-spectrophotometric method with methylene blue was first applied to the microdetermination of boron in sodium metal and UF6. The sample of sodium metal was taken and weighed in the glovebox filled with argon . Then sodium metal was oxidized,hydrolyzed, netralized and fluorizated with H2O,H2SO4 and HF, respectively. The 0. 5ppm of boron in sodium metal was determined with a relative error about ?%. This method can be applied to the determination of boron in sodium metal, sodium sulfate and sodium hydroxide at different grades. The species of boron in the hydrolysate of UF6 is BFr anion, so the sample can be directly analyzed. Boron contents in the range of 0. 1 to 0. 5 ppm was determined with a relative error about ?%. Six samples could be analysed in 2h.
