Effect of water hardness on surface tension and dilational visco-elasticity of sodium dodecyl sulphate solutions

[Display omitted] ► The surface activity of SDS is increased due to presence of bivalent ions. ► In presence of bivalent ions double chain surfactants like Ca(DS)2 can be formed. ► The hydrolysis of SDS is enhanced in NaCl solutions, producing dodecanol. ► Bivalent ions further enhance the SDS hydro...
