    Abstract

    This study investigates the speciation of silicates in aqueous solutions gathering information from different techniques such as ElectroSpray Ionization Mass Spectrometry (ESI-MS) and Nuclear Magnetic Resonance (NMR). The analysis by mass spectrometry of supernatant solutions from the partial dissolution of silicalite-1 permits to observe a whole range of silicate species that might play an important role in the crystal growth of silicalite-1. Many species ranging from the trimer to the 31-mer have been monitored. and unambiguously identified with help of the high accuracy mass measurements and isotope distributions. The presence of doubly charged species in the ESI-spectra is shown and fragmentation experiments further substantiate their identity. © 2008 Elsevier B.V. All rights reserved.
