It is well known that the active water was with prepared various energies. But, the cause of activation is still unknown. In this report, we studied the evaluating methods for the active water by the electric high voltage charging. An attempt to measure the chemical species in water by spectroscopic analysis has been done using ascorbic acid, K_4[Fe(CN)_6]and Fenton reagent as the chemical indicator. It was found that the oxidative species in active water were reduced from the absorbance difference at λ max. It is expected the measuring methods will be useful to the evaluating the active water.
