Aqueous NaHCO3 (0.23 g/ml) was sonicated for 1 week to 1 month. A 50-µl portion of the resulting soln. was analysed by Dionex anionic chromatography on a column of Ion Pac AS4A with an Ion Pac AG4A guard column and a mobile phase (2 ml/min) of 4.9mM-sodium borate decahydrate (no detection details given). The production of acetate and formate vs. sonication time was exponential. A proposed mechanism for acetate and formate production is given.

Abstract
Aqueous NaHCO3 (0.23 g/ml) was sonicated for 1 week to 1 month. A 50-µl portion of the resulting soln. was analysed by Dionex anionic chromatography on a column of Ion Pac AS4A with an Ion Pac AG4A guard column and a mobile phase (2 ml/min) of 4.9mM-sodium borate decahydrate (no detection details given). The production of acetate and formate vs. sonication time was exponential. A proposed mechanism for acetate and formate production is given.File in questo prodotto:
