The use of a polished silver solid amalgam electrode (p-AgSAE) and the square wave voltammetry (SWV) in the electroanalytical determination of Ziram herbicide in natural water samples is reported. The experimental and voltammetric parameters were optimized at 0.04molL−1 Brinton-Robinson buffer (pH 7.0), with a pulse potential frequency of 80s−1, pulse amplitude of 30mV, scan increment of 2mV and the...
