Figure 3From: Effects of concentration, temperature and solvent composition on density and apparent molar volume of the binary mixtures of cationic-anionic surfactants in methanol–water mixed solvent media Concentration dependence of density for sodium dodecyl sulphate in presence of cetyltrimethylammounium bromide at 323.15 K, in pure water (triangles) and different methanol–water mixtures (squares, in 0.1 volume fraction of methanol; circles, 0.2 volume fraction of methanol; crosses, 0.3 volume fraction of methanol).
