用苯基荧光酮 -溴化十六烷基三甲铵 -十二烷基苯磺酸钠增溶吸光光度法测定酸性水相中微量锗。选择 50 5nm为工作波长 ,并对表面活性剂用量、显色时间、显色剂用量和酸度的影响进行了讨论。加入十二烷基苯磺酸钠溶解了固体样品消化后易出现的红色絮状物 ,取得较好效果
Determination of Trace Germanium in Acidic Aqueous Solution by Phenylfluorone - Cetyltrimethylammonium Bromide - Sodium Dodecylbenzenesulfonate Solubilization Spectrophotometry. Choose 50 5nm as the working wavelength, and the amount of surfactant, color time, the amount of developer and acidity were discussed. Addition of sodium dodecylbenzenesulfonate dissolves the red floc that easily appears after the solid sample digestion and achieves better results
