The performance characteristics of methods (accuracy, reliability, repeatability, reproducibility, sensitivity, detection limit, limit of quantification, the work domain) permit their introduction into the analysis of inorganic compounds in environmental samples for surface water, groundwater and drinking water at trace levels (μg/l or ng/l).en-USElectrochemical methodsStripping voltammetrySpeciationMetalsProject
