文摘
- •
The solubilisation constants (Ks) of 4-chlorobenzoic acid in aqueous solutions of various surfactants are determined by the UV–Vis spectrophotometric method.
- •
The effects of head- and tail-groups on the solubilisation of 4-chlorobenzoic acid have been studied.
- •
A synergistic effect is happened at the solubilisation of 4-chlorobenzoic acid by LSB/nonionic mixed systems.
- •
The iso-structural temperatures are increased with the increase of the alkyl chain-length of surfactant for each system but not severely depending on the head groups of surfactants.
