The Water Sample Mercury Ion (Hg²⁺) Concentration Assay Kit is primarily used for detecting and quantifying mercury ions in water samples. It is widely applied in environmental monitoring to assess water quality, particularly in identifying contamination from industrial discharges, mining activities, or natural sources. This kit is essential for laboratories and research institutions focused on ensuring compliance with environmental regulations and safeguarding public health. It is also utilized in studies investigating the impact of mercury pollution on aquatic ecosystems and biodiversity. Additionally, the kit supports water treatment facilities in evaluating the effectiveness of mercury removal processes. Its ease of use and accuracy make it a valuable tool for both routine testing and emergency response scenarios involving mercury contamination.
