Continuous measurement of copper concentration in aqueous solutions with highly changing physico-chimical parameters

Continuous measurement of heavy metals in waste water without sampling and without adding reagents is one of the main objectives of our work. We propo se to adapt the potentiometric technique so as to know the concentration of copper in solutions that reproduce the variations of waste water (T, sigma , pC(C nu)) through multiparameter measurement. We show that the measure ca n be extended to the hydroxyl complexation by introduceing the pH in Nernst 's equation. The modelisation and the results are then discussed.
