The adsorption of anionic surfactants (sodium dodecyl sulfate (SDS) and sodium bis[2-ethylhexil]sulfosuccinate (AOT)) on hydrotalcite (HT) and the adsorption of 2,4-dichlorophenol (DCP) on HT and its modified forms from aqueous solutions was studied.

Methyl esters of coconut oil (CME) and the saturated fraction of palm oil (PME) were prepared from precursor oils by transesterification. Phase diagrams of oil (CME or PME)/water/non-ionic surfactant (Synperonic 91/4) were studied as a function of sy
