本文研究了在非离子型表面活性剂ＴｒｉｔｏｎＸ—１００（或称ＯＰ）存在下，苯芴酮和锗的胶束增溶光度法的显色条件、干扰离子的影响及其消除方法。结果表明显色体系的最佳条件为：１－３Ｎ硫酸；５—８ ×１０－５Ｍ苯芴酮；５－１０％乙醇；０．３－０．６％的ＯＰ；络合物在５０８ｎｍ处呈最大吸收。表观克分子吸光系数为１．３ ×１０５； 遵守比尔定律范围为０．０５—０．３ｐｐｍ的锗 （１厘米比色池）或１０—７０ｐｐｂ（５厘米比色池）。用等克分子系列法测定了在ＯＰ存在下，锗和苯芴酮的组成比为１：２。大量外来离子没有干扰，并且扩大了对Ｇｅ通常有严重干扰离子的允许量；尤其是当联用酒石酸、抗坏血酸、氨荒乙酸（ＴＣＡ）、氟化铵及ＥＤＴＡ时，可以允许存在Ｗ（Ⅵ）（２５）、Ｍｏ（Ⅵ）（１００）、Ｓｎ（Ⅳ）（３０）、Ｎｂ（Ｖ）（２５）、Ｓｂ（Ｖ）（５０）、Ｔａ（Ｖ）（１）－（括号内为锗的倍数）。选择性比相应的阳离子型［７，８］或阴离子型［１６］表面活性剂高得多。在掩蔽剂存在下络合物至少稳定二小时以上（２５℃）。初步将本法应用于测定阳极泥中的锗，与萃取法的结果相符合，从而提供了不经分离而直接在水溶液中测定某些样品中微量锗的可能性。
In this paper, the conditions of micellar solubilization of benzofluorenone and germanium in the presence of nonionic surfactant TritonX-100 (or OP) were discussed. The results showed that the optimum conditions for the color system were: 1-3N sulfuric acid; 5-8 × 10-5M phenyl fluorenone; 5-10% ethanol; 0.3-0.6% OP; complex at 508nm Was the maximum absorption. An apparent molar absorptivity of 1.3 × 105; germanium (1 cm cuvette) or 10-70 ppb (5 cm cuvette) with Beer’s Law in the 0.05-0.3 ppm range. The molar ratio of germanium to benzofluorenone was 1: 2 in the presence of OP, determined by the series of equimolar molecular methods. Large amounts of extrinsic ions do not interfere and the amount of gravimetric interference with Ge is typically extended; this is especially the case with the combination of tartaric acid, ascorbic acid, ammonia acetic anhydride (TCA), ammonium fluoride and EDTA, (25), Mo (Ⅵ) (100), Sn (Ⅳ), Nb (V), Sb (V) and Ta (V) multiple). The selectivity is much higher than that of the corresponding cationic [7,8] or anionic [16] surfactants. The complex is stable for at least two hours (25 ° C) in the presence of a masking agent. The preliminary application of this method to the determination of germanium in anode slurries conforms to the results of the extraction process, thus providing the possibility of determining trace amounts of germanium in some samples directly in aqueous solution without isolation.
