Preservation and Field Speciation of Inorganic Arsenic Species in Groundwater
This research describes the development of a dual preservationand field-speciation technique for As(III) and As(V) speciation of a sample preserved with ethylenediaminetetraacetic acid (EDTA) and acetic acid (HAc). The new method was compared with existing preservationand field-speciation methods and was shown to be accurate and precise in spite of possible interference from ferrous iron in the...
متن کاملSpeciation of Arsenic in Groundwater and Technologies for Removal of Arsenic in Drinking Water in the Spiro Tunnel Bulkhead
Application of an anion exchange resin column was performed to speciate of arsenic (III) and (V) in drinking water. This methodology was used to analyze water samples collectioned from the study of arsenic removal by two technologies, reverse osmosis membrane filtration and chemical coagulation/ filtration in pilot scale in anticipation of EPA=s new arsenic drinking water standard of 10 μg/L ta...
متن کاملGroundwater Quality and Arsenic
Water Pollution is an alarm at the global level. The groundwater is continuously decreasing, in anthropogenic pressure as well as naturally. Arsenic is one of the prominent contaminant, which is degrading the quality of groundwater naturally. In India, arsenic pollution in groundwater is mainly reported from West Bengal. Since its first reported case in early eighties, there are 1312 affected v...
متن کاملUnraveling Health Risk and Speciation of Arsenic from Groundwater in Rural Areas of Punjab, Pakistan
This study determined the total and speciated arsenic (As) concentrations and other health-related water quality parameters for unraveling the health risk of As from drinking water to humans. Groundwater samples (n = 62) were collected from three previously unexplored rural areas (Chichawatni, Vehari, Rahim Yar Khan) of Punjab in Pakistan. The mean and median As concentrations in groundwater we...
متن کامل1 Arsenic removal from groundwater using iron
10 11 We demonstrate that electrocoagulation (EC) using iron electrodes can reduce arsenic 12 below 10 µg/L in synthetic Bangladesh groundwater and in real groundwater from 13 Bangladesh and Cambodia while investigating the effect of operating parameters that are 14 often overlooked, such as charge dosage rate. We measure arsenic removal performance 15 over a larger range of current density tha...
