Mercury determination in natural, surface, sea, drinking, bottled, mineral, and waste water by cvaas
Mercury determination in natural, drinking, and waste waters is one of the most popular analyses used for environment pollution and sanitary control. Background concentrations of mercury in natural water are within several ng/l. Maximum national permissible levels for mercury in water lie in the range of 0.16–6 µg/l. For example, the following limits for mercury in drinking water are set, µg/l:
0.5 – Japan, Russia;
1 – Argentina,...

All described properties of Fe(0) nanoparticles can be even used for decomposition of pollutants contained in the waste water, mainly for treatment of industrial sewage and hutch water. The usage of nanoiron can represent a significant qualitative step in the classical technologies of water treatment including drinking water. The extremely reactive iron nanoparticles thus offer a possibility to solve long-lasting problems with a high content of uranium and arsenic in a variety of localities in the Central...

Context & Challenges Volatile organic compounds (VOC) can be dissolved in water. Sometimes water is polluted and to study contamination of VOC in finished drinking water, VOC must be measured. Chromatotec® Solutions Chromatotec® has developed a specific system for the measurement of VOC in water: a Purge & Trap system, the airmoPURGE. The analyzer is coupled with a degasing system allowing the extraction of dissolved gases. The complete system is based on: - 502.2 method from US EPA –...

Laboratories that analyze drinking water and wastewater form a critical component of our public health infrastructure, guided by criteria in legislation including the Safe Drinking Water Act (SDWA) and the National Pollution Discharge Elimination Program (NPDEP). These facilities are required to handle high volumes of sewage and drinking water to analyze for wet chemistry and microbiology before discharge into community water systems. This requires the facilities to maintain continuous sampling programs,...

Sewer management is crucial to the sustainability of life. It is necessary to properly discharge wastewater clinically and efficiently. Failure in wastewater systems will cause major implications in the future. The population is increasing, and larger volumes of wastewater put additional strain on existing sewer infrastructure. Each year there are nearly 75,000 such overflows in the United States, discharging approximately 900 billion gallons of untreated sewage into lakes, streams, and rivers. This...
