The pH was circumneutral.
Optimal pH is located around circumneutral conditions.
At circumneutral pHs, ZnO NPs were positively charged and immobile in sand.
Polysulfides are readily formed at the circumneutral pH and elevated temperatures [31].
Circumneutral pH was found to be favorable for the adsorption of CR onto GO.
At circumneutral pH, the surface properties of montmorillonite and OM molecules are relatively pH-insensitive.
Furthermore, these data indicate that circumneutral pH foods pose a much smaller risk for exposure.
Glucose activation of persulfate increased as a function of sodium hydroxide addition, but was still effective at circumneutral pH regimes.
The hydrothermal sites were moderately acidic (pH 4.0-5.7) and those from background sediments were circumneutral (pH ~ 7.4).
The present study focuses on redox reactions of ferrous iron (Fe(II)) with oxidized Mn(IV) solids at circumneutral pH.
During all seasons, pH values are circumneutral with little variation with depth below the sediment water interface (SWI; Fig. 1).
