十二烷基磺酸钠-正戍醇混合胶束研究

On the mixed mieelle of sodium dodeeyl sulpnonate-n-pentyl acohol

本文用电导法在313. 2K、318. 2K、323. 2K,328. 2K 下测定含0. 2mol/L 正戍醇(PAH)的十二烷基磺酸钠(SDS)水溶液的临界胶束浓度 CMC、胶束中 SDS 分子解离度α、胶束中 PAH 含量 Xa 以及胶束生成焓△H^0m。讨论了温度对含 PAH 的 SDS 溶液的 CMC、α、Xa 及△H^0m 的影响规律。

The critical micelle concentration CMC of sodium nomal dodecyl sulphonate containing n-pentyl acohol,the dissociation degree a of the molecule of sodium dodecyl sulphonate in the micelle,the content rate Xa of the pentyl acohol in the micelle and the enthalpy change (?) of micelle formation--all these are measured by conductivity measurement at temperature of 313. 2K、318. 2K、323. 2K、328. 2K.Meanwhile,we disscused the influence of the temperature on the CMC、α、Xa and ■。
