Square wave adsorptive stripping voltammetry of nickel and cobalt at wall‐jet electrodes in continuous flow

Abstract

Abstract Square wave adsorptive stripping voltammetry (SWAdSV) of nickel and cobalt at wall‐jet electrodes in a continuous flow system has been evaluated. Characteristics and advantages relative to differential pulse adsorptive stripping voltammetry (DPAdSV) in continuous flow systems are explored. Under optimized experimental conditions, sensitivity is approximately a factor of ten higher than DPAdSV, and one‐nanomolar detection limits are achieved. Solution deoxygenation is unnecessary and sample throughput is increased.
