a) separate protonation of purified potable water with a proton donor stronger than water selected from a group including orthophosphoric acid and carbonic acid in the amount of from 0.05 to 0.2 wt.%, and of rectified ethanol with a protondonor stronger than the alcohol selected from a group including hydrochloric acid, citric acid, ascorbic acid, oxalic acid in the amount of from 0.1 to 0,5 wt.%,
b) separate filtration of the target products obtained at step a) using the technique of sodium cation exchange and reverse osmosis,
c) mixing filtered products obtained at step b).
