PROCESS FOR MANUFACTURING AN AMPEROMETER SENSOR FOR DETECTING OXYGENATED WATER ON THE BASIS OF CARBON PASTE ELECTRODE MODIFIED WITH A NATURAL ZEOLITE ENRICHED WITH COPPER

摘要

The invention relates to a process for preparing a sensor for detecting oxygenated water. According to the invention, the process consists in contacting the zeolitic volcanic tuff in sodic form with copper sulphate having concentrations of 0.2...0.5 N, in static regime, for 24 h, wherefrom there results a natural zeolite enriched with copper, which is mixed with powder graphite and paraffin oil, there resulting the modified carbon paste which is introduced inside a teflon body, for assembling the electrode.
