在胶束增溶分光光度法中作为增感剂,用得最多的是阳离子型及非离子型表面活性剂。至今尚未见有使用阴、阳离子型表面活性剂的。我们认为,这些表面活性剂胶束的基本性质,互有异同,见实验部分 (一)表面活性剂的合成 1.溴化辛基三甲铵[C_3H_(17)N(CH_3)_3。Br]:以氢溴酸-硫酸法自正辛醇制得1-溴代辛烷,使与过量的33％三甲胺-乙醇液反应,制成。产品以乙醚抽提8小时以上。本品有吸湿性,应贮存于P_2O_5乾燥器中,称取时需用称量瓶。表1。为了探明各类表面活性剂的作用,我们研究了溴化辛基三甲铵-硫酸辛酯钠-铬天青S-铝(Ⅲ)体系的分光光度性质。
In micellar solubilization spectrophotometry as a sensitizer, the most frequently used are cationic and non-ionic surfactants. To date, no anionic or cationic surfactants have been used. We believe that the basic nature of these surfactant micelles, similar to each other, see the experimental part (a) Synthesis of Surfactants 1. Octyltrimethylammonium bromide [C_3H_ (17) N (CH_3) _3. Br]: Hydrobromic acid - sulfuric acid from n-octanol obtained 1-bromo-octane, with an excess of 33% trimethylamine - ethanol solution made. Products extracted with ether more than 8 hours. This product is hygroscopic, should be stored in P_2O_5 desiccator, weighing the need to use weighing bottles. Table 1. In order to explore the role of various surfactants, we investigated the spectrophotometric properties of the octyltrimethylammonium bromide-sodium octylsulfate-chromium azure S-aluminum (III) system.
