Assessment of Boron Doped Diamond Electrode Quality and Application to In Situ Modification of Local pH by Water Electrolysis
Published on: January 6, 2016
Abstract:
In samples of normal table water, the level of pH is significantly lower than that of reference samples, when an aliquot of water originating from the springs close to the sanctuary to the Virgin Mary at Lourdes at a final dilution rate of 1:400,000 parts has been added to the sample of water tested. The differences as compared to the reference waters, that is those samples to which the aliquot of Lourdes water were not added, were tested by analysis of the variance and were found to be highly significant. The measurements were conducted on approximately 600 samples. It was demonstrated that the phenomenon observed could not be attributed to chemical species present in the Lourdes water which can justify the lowering of the pH in relation to the dilution rate with which the work was performed.
