A simple voltammetric determination of metsulfuron-methyl in water samples using differential pulse cathodic stripping voltammetry

The voltammetric determination of metsulfuron-methyl, a type of pesticide, was investigated on a hanging mercury drop electrode using a differential pulse cathodic stripping voltammetry technique. The experimental parameters, such as the pH of the Britton-Robinson buffer, accumulation time, accumula...
