摘要: The adsorption of sodium oleate and various ethoxylated nonylphenol surfactants their mixtures at air/liquid interface was investigated by equilibrium dynamic surface tension experiments. Synergism determined observing the lowering water single mixtures. results showed that addition nonionic surfactant reduced both solutions. effect molecular weight, HLB, degree ethoxylation studied. Interaction between anionic calculated using an interaction parameter. parameter NP‐4 (a surfactant) to be −0.21, showing attraction two molecules.
