盐水振荡与液膜振荡耦合 总被引:1,自引:0,他引:1
为进一步增大盐水振荡产生的电势差,并使盐水振荡可逆,该文将液膜振荡与盐水振荡耦合,组成一个耦合的振荡器.实验结果发现:(1)由于两振荡器耦合形成共振,所以此耦合振荡器的振幅明显增大; (2)耦合后的化学振荡器变为可逆振荡器.耦合振荡机理如下:扩散过程中形成的缔合物存于油相,难溶于水,通电后缔合物发生解离,因此造成反扩散,形成可逆振荡,且可逆程度及逆反应产生的电势差(即振幅)大大提高,扩展了盐水振荡在二次电池开发方面的应用. 相似文献

穿过液膜的自发电势振荡 总被引:2,自引:0,他引:2
An artificial membrane consisting of pricramic acid in nitrobenzene was used as an oil phase imposed between two aqueous phases. The right one contained trimethyl-slearylammonium chloride and aicohol; and the left contained sucrose solution (or H_2O). We found that this system exhibited rhythmic oscillation of electrical potential. The amplitude of the oscillations was between 20—150 mV. The oscillations were observed even when ethyl alcohol was absent in the aqueous of trimethylslearylammonium Chloride, and the increase in amplitude of oscillation with time was found to be less in the presence of sucrose. Some of the expremental results have been explained. 相似文献

Liquid Membrane Oscillation of Water/Oil/Water System Containing TTAB and Recognition to Amino Acids
The liquid membrane oscillation of a novel water(aqueous tetradecyl trimethyl ammoniumbromide,TTAB and alcohol solution)/oil(picric acid in chloroform solution)/water(aqueous glucose solution) system was investigated by means of a homemade device.The results show that the water(aqueous 7 mmol/L TTAB and 0.5 mol/L n-propanol solution)/oil(0.5 mmol/L icric acid in chloroform solution)/water(0.1 mol/L glucose solution) system performed sustained and stable oscillation at 30 °C.The oscillation curve under optim... 相似文献

反相液相色谱法分离烷基苯磺酸钠同系物及其异构体 总被引:3,自引:0,他引:3
1 引 言烷基苯磺酸钠表面活性剂广泛用于许多领域 ,传统的分析方法只能用于分类鉴别。现代分析技术包括气相色谱法(GC)、高效液相色谱法 (HPLC)和毛细管电泳 (CE)已广泛用于烷基苯磺酸钠的分离分析。由于烷基苯磺酸钠难以挥发 ,GC的应用受到限制 ,CE未实现烷基苯磺酸钠异构体的分离 ,HPLC具有可直接分析、分离模式多、检测方便等优点 ,广泛用于烷基苯磺酸钠的分析。HPLC已成功实现了烷基苯磺酸钠同系物分离 ,而对异构体的分离不完全 ,且报道不多。本文采用C18反相色谱柱、流动相中添加磷酸二氢钠电解质的液相色谱… 相似文献
