Determination of mercury traces in sanitary landfill leachates by anodic stripping voltammetry.
Particular attention is being paid to the presence of heavy metals--especially mercury--because of their tendency to accumulate in water. These toxic and persistent substances in the environment continuously accumulate and increase as a result of anthropogenic activity (Sonthalia et al., 2004). This paper presents the detection and measurement of the amount of dissolved mercury in young and mature leachates of a sanitary landfill, where the young leachates have had a technical environmental treatment compared with the mature leachates, using differential pulse anodic stripping voltammetry as an instrumental technique. The results showed significant differences in mercury content in both leachates.
