8-羟基喹啉是最常用的有机试剂之一。有关它和它的金属络合物已有专著系统报道。但8-羟基喹啉在碱性溶液中半醌式异构化产物及其铋络合物的极谱行为尚未见报道。我们发现,它的异构化产物与某些金属离子形成的络合物,不仅能在电极上产生吸附,从而使去极剂得到富集,而且异构化产物做为配体,能够被金属离子的还原诱导产生极谱电流,使测定的 8-hydroxyquinoline is one of the most commonly used organic reagents. There are monographs about it and its metal complexes. However, the polarographic behavior of 8-hydroxyquinoline in semicarbazone isomerization products and their bismuth complexes has not been reported. We found that its isomerization products and some metal ions formed complexes, not only in the electrode adsorption, so that the depolarizer is enriched, and the isomerization product as a ligand, can be metal Reduction of ions induces a polarographic current that produces a measured
