A new chromate-selective electrode, based on the N, Nי butylen bis (saliciliden iminato) copper (II) complex as the membrane carrier, was developed. The electrode exhibited a good Nernstian slope of -28.8(plus-minus) 0.5 mV/decade and a linear range of 3.0 x 10^- 6 - 1.0 X 10^-1 mol.l ^-I for chromate. The limit of detection was 3.0 x 10^-6 mol.l^- I . It had a fast response time of 5-10 sec and could be used for more than three months. The selective coefficients were determined by the Fixed Interference Method (FIM). A chromate-selective electrode could be used in the pH range of 6.5-10.5. It was employed as an indicator electrode for the direct determination of chromate in real samples.
