摘　　要：研究了电解质NaCl、CaCl2和MgCl2对十二烷基二苯醚双磺酸钠水溶液/癸烷间界面张力的影响.NaCl、CaCl2和MgCl2的加入可以降低界面张力,且界面张力保持在10-1m N/m数量级.随着电解质浓度的增加,界面张力达到平衡所需时间减少.CaCl2和MgCl2质量浓度对平衡界面张力的影响基本一致.同时加入电解质NaCl和CaCl2,当NaCl质量浓度增大时,CaCl2质量浓度对界面张力达到平衡所需时间的影响减小.The effect of electrolyte （NaCl, CaCl2 and MgCl2） on interfacial tension of disodium dodecyl diphenyloxide disulfonate aqueous solution and decane was investigated. Addition of NaCl, CaCl2 or MgCl2 could decrease interracial tension, and the interracial tension could be kept in the range of 10^-1 mN/m. The time required for interracial tension to reach equilibrium decreased with the increase of electrolyte concentration. Effect of CaCl2 and MgCl2 concentration on equilibrium interracial tension was almost the same. When NaCI and CaCl2 were added at the same time, effect of CaCl2 concentration on the time required for interracial tension reaching equilibrium decreased with the NaCl concentration increasino.
