2,3,7-三羟基-9-取代萤光酮衍生物加表面活性剂是测定锗的优良试剂,已有水扬基萤光酮,4,5-二溴苯基萤光酮测定锗的报导,以及锗与甲基萤光酮等七种萤光酮的显色反应研究,均有灵敏度高又稳定等优点,但钨、钽、钛、锡等干扰较大。海南大学奚干卿,北京化工厂梁德修为改善测定锗的选择性, The 2,3,7-trihydroxy-9-substituted fluorone derivatives and surfactants are excellent reagents for the determination of germanium. Fluorescent ketone has been used as a water-solubilizing agent, and germanium has been measured with 4,5-dibromophenylfluorone , As well as the study of the color reaction of seven kinds of fluorone ketones such as germanium and methyl fluorone, have the advantages of high sensitivity and stability, but the interference of tungsten, tantalum, titanium and tin is large. Xi Ganqing, Hainan University, Beijing Chemical Plant Liang Defu to improve the determination of the selectivity of germanium,
