在一般的有色金属及合金中铋是有害杂质,需要控制其存在量。因此在金属分析中铋的快速测定具有广泛的要求(表1)。测定痕量铋一般常采用碘化物比色法或二苯硫腙萃取吸光光度法等。我们曾报导了应用碘化钾-马钱子碱萃取吸光光度法测定微量铋。
In general, non-ferrous metals and alloys bismuth is harmful impurities, the need to control the amount of its existence. Therefore, the rapid determination of bismuth metal analysis has a wide range of requirements (Table 1). Determination of trace bismuth commonly used iodide colorimetric or diphenylthio hydrazone extraction spectrophotometry. We have reported the determination of trace bismuth using potassium iodide-brucine extraction spectrophotometry.
