Base line subtraction systematic error estimation for mercury determination by stripping voltammetry in environmental objects

Abstract

In most cases the correct estimation of the systematic error of analytical chemistry methods is complicated by the random error, conditioned by irreproducibility of some experimental factors. In stripping voltammetry the appreciable systematic error connected with the residual current (base line) subtraction can appear. The stripping voltammetry feature is absence of information about the base line shape under the peak. The modelling of analytical signal with the addition of the experimental base line for the systematic error estimation of mercury determination by stripping voltammetry with gold-film electrode in the environmental objects are proposed. The systematic error dependences on the relative magnitude of analytical signal of mercury were obtained. The proposed procedure of systematic error compensation allows to reduce the summary error of stripping voltammetry mercury determination in the environmental objects (water samples).
