  • Nitrate Analysis of Water Samples Using a Benchtop UV-Vis Spectrophotometer

    Nitrogen is naturally found in groundwater and surface water in the form of nitrate, nitrite, or ammonium. The EPA has established a maximum contaminant level of nitrate-nitrogen in potable water of 10ppm. This application presents results of UV-Vis analysis of nitrate concentrations in drinking water, ground water, and industrial wastewater, showing that the manual colorimetric method is ...

  • Mineral oil contaminations in cardboard

    SpeedExtractor E-916: Optimization of pressurized solvent extraction (PSE) for the rapid and efficient determination of MOSH and MOAH in cardboard Many food samples are often contaminated with mineral oil coming from different sources. One possible source of contamination is the migration from cardboard packaging made of recycled fibres. ...

  • Protoc TOC succes at Manchester Airport

    The case study outlines the installation of Protoc TOC analysers at Manchester International Airport used for continuous surface water quality monitoring and control. The Protoc TOC instrument manufactured in the UK by Pollution & Process Monitoring Ltd was rigorously tested and was selected for a number of installations at critical drainage locations which have proved the reliability of the ...

  • Evaluation of mutagenic activity of organic micropollutants present in surface waters

    Surface water to be employed in drinking water supplies can be characterised both by chemical analysis and mutagenic activity in order to detect genotoxic compounds present as environmental pollutants or produced by drinking water treatments. In our experimental conditions, only two samples out of seven raw and four processed water extracts (Amberlite XAD-2 concentration) gave mutagenic effects ...

  • Mop Water Treatability

    The samples were tested at our facility on Thursday, March 20, 2003. Visually the samples were a homogeneous mixture of mop water, oil, and metals. The initial pH was 10.5 and the conductivity was 7,500 μS.The sample was ozonated at a setting of 35% of capacity (35% of 3.9 gm/hour) or 1.37 gm/hour in the stabilization column for 12 hours. There appeared to be very little separation of oils ...

  • Choosing the appropriate TOC analyzer for your application?

    In choosing a Total Organic Carbon (TOC) analyzer, among the many factors that need to be given consideration are not only the current instruments and their accessories available on the market, but specifically to their method of sample oxidation in relation to the sample matrix. Different oxidation techniques may affect the analytical data due to the components within the sample matrix. This ...

  • The Effects of Particle Shape and Surface Roughness on the Hydraulic Mean Radius of a Porous Medium Consisting of Quarried Rock

    The influence of particle shape and surface roughness on the hydraulic mean radius are investigated, and quantitative measures for each are proposed. A particle shape factor is estimated with the aid of a new mathematical approximation for the surface area of an ellipsoid. The particle surface roughness is calculated based on inferences made from surface area data previously obtained for a sample ...

  • Rapid Quantification of Perfluorinated Compounds in Drinking and Surface Water Using LC-MS/MS

    As contaminants of emerging concern, research on PFCs is ongoing to determine the impacts of these materials on human health and the environment. A CDC study detected four of these analytes in >98% of serum samples representative of the general US population above age twelve. Low level analysis of these compounds is challenging due to their ubiquitous presence in the laboratory and analytical ...

  • The effects of industrialisation on water quality and livelihoods in Lesotho

    In Lesotho, some of the industrial wastewater discharges are being released untreated into the environment causing water pollution. This study investigates the extent and impacts of industrial water pollution in Lesotho and the associated effects on human livelihoods in the region. A combination of desk studies, in-field water sampling and socio-economic survey showed that industrial effluents ...
