| Abstract: | The effect of inorganic electrolytes with salting-in and salting-out nonionic surfactant TX - l00 (Na_2SO_4 and KSCN) on the interaction between negative ion dye(ECAB) and TX -- l00 was investigated. The binding constant K of dye with TX - l00 micelles and CMC of three systems were obtained. For ECAB + TX - l00, ECAB + TX - l00 + Na_2SO_4and ECAB + TX - l00 + KSCN systems, K and CMC were 2550, 7532, 2400dm_3 mol~(-1)' and 2. 5 × 10~(-4), 1. 87 × 10~(-4), 1. 83 x 10~(-4)mol' dm~(-3) respectively. The results were qualitatively interpreted. |
