Influence of the Interfacial pH on Electrochemical CaCO[sub 3] Precipitation
The influence of the pH at the electrode/solution interface on precipitation by means of electrochemistry was studied both theoretically and experimentally in pure calcocarbonic aqueous solutions. This interfacial pH was measured at the electrode by using a pH sensor-grid assembly in a submerged imp...

The influence of the pH at the electrode/solution interface on precipitation by means of electrochemistry was studied both theoretically and experimentally in pure calcocarbonic aqueous solutions.
