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,二溴代苤硒脑的极谱特性及应用尚未见报道,本文研究了硒(Ⅳ)与二溴代邻苯二胺(简称DBDA)所生成的4,6-二溴代苤硒脑(简称PIS)的极谱行为,发现PIS在汞电极上于-0.1V(vs.AgCi/Ag)左右产生一良好的灵敏极谱波,研究了极谱
Selenium (Ⅳ) and o-aromatic diamines can generate the corresponding selenium derivatives, and the polarographic properties of selenium and dibromo-selenium can be determined by polarography using their electroreduction properties and their applications have not been reported. The polarographic behavior of selenium (Ⅳ) and dibromo-o-phenylenediamine (DBDA) generated 4,6-dibromoquinane selenium (PIS) was studied. (vs. AgCi / Ag) produced a good polarographic polarographic wave and studied the polarographic spectrum
