Here, we use Received 10 November 2017 NaOH solutions to investigate basic environments. Revised 8 January 2018 Simulations: Sodium adsorption on hydroxylated silica surfaces from NaOH solutions were investigated Accepted 12 January 2018 through molecular dynamics with a dissociative force ﬁeld, allowing for the development of secondary Available online 16 January 2018 molecular species. Findings: Across the NaOH concentrations (0.01 M 1.0 M), 50% of the Na ions were concentrated in the Keywords: 2 2 surface region, developing silica surface charges between 0.01 C/m (0.01 M NaOH) and 0.76 C/m Adsorption (1.0 M NaOH) due to surface site deprotonation. Five inner-sphere adsorption complexes were identiﬁed, Silica including monodentate, bidentate, and tridentate conﬁgurations and
