摘要： 硒(Ⅳ)与邻芳香二胺类试剂能生成相应的苤硒脑衍生物,利用其电还原性质可用极谱法测定硒[1,2],二溴代苤硒脑的极谱特性及应用尚未见报道.

Abstract: In this paper the polarographic behaviour and mechanism of adsorption wave of 4,6-dibromopiaselenole(4,6-diBr-PIS) in several mediums are studied by cyclic voltammetry and differential neopolarography.In weak acidic medium 4,6-diBr-PlSgave a sensitive irreversible adsorption wave (Epc = -0.1Vvs.AgCl/Ag electrode) on mercury electrode.The wave could be used as basis of the sensitive semi-differential neopolarographic method for the determination of trace selenium.
