ABSTRACT
Calcareous scaling on domestic and industrial equipments generates severe problems and causes drastic economic loss. The use of several chemicals is a common technique to impede the scale deposition. The subject of this study is the inhibition of the scaling process. Thus, we have followed the coverage of a titanium electrode, in absence and in presence of two anti-scale products, using the chronoamperometry. The mineral scales were characterized by electrochemical impedance spectroscopy (EIS) and analyzed by electronic sweeping microscopy (ESM). It was found that 25 ppm of hydroxyl-2 m├ęthyl-4 benzylphosponic acide (AHMBP) or of Diprochim anti-scale is sufficient to prevent electrodeposition. The efficiency of the two chemicals is comparable.
