Abstract

In the present work, the structure-directing effect of the surfactant sodium dodecyl sulfate (SDS) on the distribution of the silicate species present in alkaline aqueous silicate solutions is studied using silicon-29 nuclear magnetic resonance (NMR) spectroscopy. Also, the distribution of silicate anions in the presence of polyelectrolytes is investigated using 29Si NMR spectroscopy through the use of different bases including tetraoctylammonium hydroxide and sodium hydroxide as templates (their cations) in these solutions. Both the SDS and polyelectrolytic solutions are shown to stabilize low molecular weight silicate species and thus inhibit polymerization.
