Identification of Arsenic in the Water Using Energy Dispersive X-Ray Diffraction

Abstract

The occurrence of arsenic in natural water has received significant attention during recent years. The arsenic plays an important role for its behavior and toxicity in the aqueous system. Arsenic is a toxic pollutant in water with serious health effects upon long-term intake of even low concentrations through drinking water consumption population. By means of the energy-dispersive X-ray diffraction (EDXRD) technique, confected different concentrations of sodium arsenate solution and reservoir water of Tuoketuo county in the Inner Mongolia, were analyzed. The result shows that arsenic is present within reservoir water of Tuoketuo county. But, fluorescence peak photons of arsenic in the solution are not in proportion to the concentration. So, it is difficulty to quantitatively decide the concentration of the arsenic in the water.
