Abstract: The presence of heavy metals in the wastewater is harmful for human being. The waste water containing metal ions can contaminate water resources. These metals enter human bodies through food and water. In order to understand the heavy metal concentration from wastewater, it is desired to have effective, accurate but simpler and low cost method for heavy metals. Various methods such as atomic absorption spectroscopy, X-ray diffraction, chromatography and other advanced analysis techniques are available for this purpose. U.V. Spectrophotometer promises cost effective solution to the analysis of heavy metals. Thus 2-Acetylpyridine thiosemicarbazone (APT) is used as new analytical reagent for the direct non-extractive spectrophotometric determination of Hg (II) Metal. The method is successfully applied for the determination of mercury in a number of water samples (potable and polluted) collected from different points of Rani Pokhari of Kathmandu, Nepal.
