  • On the suitability of Portable X-Ray Fluorescence Analyzers for rapid screening of toxic

    Abstract X-Ray Fluorescence spectrometry (XRF) has been routinely used for alloy testing, determination of Pb in paint, and determination of Cd in plastic. However, its use to screen for toxic elements in food and medicinal products has been surprisingly limited to date. While XRF is less sensitive than atomic spectrometry methods such as ICP-AES and ICP-MS, it offers a number of significant ...

  • Screening technique to estimate high benzo[a]pyrene concentrations near roads

    The emission factors of benzo[a]pyrene for gasoline cars and for diesel cars were measured by directly collecting the exhaust gas using a portable sampling equipment and became 660 ng km–1 and 1700 ng km–1, respectively. The regression equations to easily evaluate the concentrations at the roadsides and at the crossroads were introduced as the functions of building height, road width, ...

  • Development of a portable filter for arsenic removal from drinking water

    In the present study, different grades of indigenously available activated alumina (AA) were screened for their arsenic removal capacity. For both As(III) and As(V), A1 (Grade 1, 0.3-0.6 mm) activated alumina has shown better removal efficiency. The optimum pH for the adsorption phenomena was around 7.0. Chlorine at a dose of 20 mg/l could completely oxidize As(III) to As(V), which also assured ...
