A simple method was developed for speciation and spectrophotometric determination of inorganic As(III) and As(V) using ‎an electrochemical hydride generation technique. For speciation of As(III) and As(V), a graphite rod ...

In this study, arsenic concentration and pollution in water resources of Pangi area (Kadkan, NW Torbat Hydarieh), adjacent to Sarhang- Golbou ophiolitic zone, is investigated. Results of this study indicate high concentrations of arsenic in local...

Exposure to thallium (Tl: Atomic weight of 204.38 and atomic number of 81) and lead (Pb: 207.21 and 82) are important global health-ill problem in particular in developing world.[1,2] These elements are derived from two ...

Adsorption of As(V) on various clay minerals including kaolinite (KGa-1), montmorillonite (SWy-1) and nontronites (NAU-1 and NAU-2), and subsequent bioreduction of sorbed As(V) to As(III) by

bacterium Shewanella ...
