The improvement of anodic stripping voltammetric (ASV) method of cadmium and mercury determination
2006 (English)Student paper otherStudent thesis
Abstract [en]

Among the various environmental pollutants, heavy metals such as cadmium and mercury are considered the most important. Due to high stability and ability for bioaccumulation they are extremely dangerous for all biological organisms and especially for humans. That’s why a matter of great importance is to analyze and quantify these toxic agents in the environment. In this regard, methods of analysis play not the last role. Methods are different: atomic absorption spectrometry, atomic emission spectrometry etc. Often these techniques require complex sample preparation and expensive instrumentations. In contrast, voltammetric methods particularly anodic stripping voltammetric (ASV) have some advantages such as little or no sample pretreatment and low cost instrumentation. In addition the analytical set is very compact. The aim of this work was to improve anodic striping voltammetric (ASV) methods of analysis for mercury and cadmium detection. The improved method was applied for natural water quality monitoring: some water samples from the delta of Northern Dvina River were analyzed by the method.
