✦ Synopsis

The adsorption properties of aqueous solutions of sodium alkyl sulfates and their oxyethylates have been studied systematically.

The effect of defined structural changes on the adsorption parameter values calculated on the basis of Frumkin's surface equation of state has been demonstrated.

In particular, a comparison has been made between ndodecyl and cyclododecyl as hydrophobic groups in sodium alkyl sulfate and its ethers. The limiting areas obtained by surface tension measurements have been discussed on the basis of the crystal structure data of n-dodecyl sulfate and theoretical calculations on the three-dimensional shape of selected conformers of cyclododecyl sulfate.
