sodium lauryl sulfate, 151

Sodium lauryl sulfate (SLS), sodium laurilsulfate or sodium dodecyl sulfate (SDS or NaDS) (C12H25SO4Na) is an anionic surfactant used in many cleaning and hygiene products. The molecule has a tail of 12 carbon atoms, attached to a sulfate group, giving the molecule the amphiphilic properties required of a detergent.

Adsorption of Sodium Dodecyl Sulfate on Functionalized

ABSTRACT: We report on the adsorption of sodium dodecyl sulfate (SDS) onto functionalized graphene sheets (FGSs) in an aqueous system, measured at broad SDS and FGS concentration ranges by conductometric surfactant titration. At dilute SDS concentrations (12 μM in bulk solution), there is evidence of a counterion exchange between hydronium ions

Visible Circular Dichroism of Lutein Acquired on

Lutein, one of the most common carotenoids, has been believed to be optically inactive in the visible region. Lutein was found, however, to acquire a very strong circular dichroic (CD) activity in this region when dispersed in an aqueous solution in the presence of sodium dodecyl sulfate (SDS). The CD spectrum of lutein had positive and negative extrema before and behind a crossover at about

What is the ionic compound formula of sodium sulfate

May 05, 2014Sodium Sulfate is an ionic compound formed by two ions, Sodium Na^+ and Sulfate SO_4^-2. In order for these two polyatomic ions to bond the charges must be equal and opposite. Therefore, it will take two +1 sodium ions to balance the one -2 sulfate ion. This will make the formula for Sodium Sulfate Na_2SO_4. I hope this was helpful.
