Using cyclic voltammetry technique for electrochemically analysis a new 1-pentylpyridazinium bromide (PPB) ionic liquid on surface of mercury electrode

A sharp cyclic voltammogram was observed at E_1/2 = − 0.65 V as reduction wave at phosphate buffer pH 2.5.

The cyclic voltammetric method has been explained an irreversibility of the reduction process.

PPB was had a good stability, reproducibility and recovery. Cal. curve was studied over the range 1.0 × 10^− 5 to 5.0 × 10^− 4 mol L^− 1, r² = 0.997; n = 13.

The determination of PPB was applied in the detergents and sea water samples directly.
