USING TOTAL REFLECTION X-RAY FLUORESCENSE (TXRF) TO ANALYSE TRACE ELEMENTS IN SURFACE WATER OF XUAN HUONG LAKE – DALAT CITY

Abstract

 The regular assessment of a water source has been important for safety and pollution warning. Specifically, the concentration of trace elements in water reflects the pollution level. Urbanization, industrialization, fertilizers and other plant protection products have negatively affected the environment; in particular, water and air quality. The main objective of this study was to evaluate the trace elements contained in surface water from Xuan Huong Lake – Dalat city by using the technique of Total Reflection X-ray Fluorescence (TXRF). The results show that the concentrations of some metal elements, such as Iron and Bromine, exceeded the limits by the Vietnamese standards as well as others in many countries.
