| Résumé: | Calcareous deposits in water desalination generate serious problems and lead to considerable
economic losses. The aim of this study is to investigate the inhibition of calcareous deposits
using polyphosphonate (scale inhibitor SI-4497), which is an ideal additive for desalination
operations. We studied the recovery rate of titanium electrode, in the presence and absence of
this inhibitor, using chronoamperometry. A cathodic potential of –1.3 V/SCE (SCE – saturated
calomel electrode) is used at 1,000 rpm and at 20°C, 40°C, 60°C, 80°C. Levich’s law is verified
before and after 1 h of electrodeposition in presence of an inhibitor. It was found that electrode
recovery decreases with the addition of 3.5 ppm polyphosphonate (scale inhibitor SI-4497),
resulting in an efficiency of 63.65% |
