Indigo Carmine (C16H8N2Na2O8S2), an anionic dye, was removed from aqueous solution by solvent sublation of Indigo Carmine-cetyltrimethylammonium bromide (CTAB) complex (sublate) into 2-octanol. A stoichiometric amount of surfactant (surfactant:dye=2:1) was demonstrated to be able to remove over 93% IC from the aqueous solution in 5 min. The apparent activation energy of attachment of the sublate to bubbles was calculated as 1.3 kJ/mol. Parameters were considered. At the same time, on the base of the complete transport mechanism, a mathematical model for the dye-surfactant complexation was obtained. Furthermore, the simulation of the mathematical and experimental data was made with good results.
靛蓝胭脂红（C₁₆H₈N₂Na₂O₈S₂），一种阴离子染料，通过将靛蓝胭脂红 - 十六烷基三甲基溴化铵（CTAB）络合物（被萃取物）溶剂浮选到2 - 辛醇中，从水溶液中被去除。已证明化学计量量的表面活性剂（表面活性剂：染料 = 2:1）能够在5分钟内从水溶液中去除超过93%的靛蓝胭脂红。被萃取物附着到气泡上的表观活化能经计算为1.3 kJ/mol。考虑了相关参数。同时，基于完整的传输机制，获得了染料 - 表面活性剂络合的数学模型。此外，对数学数据和实验数据进行了模拟，结果良好。
