Abstract

Analyses of trace metal elements are generally performed by expensive instrumental methods, such as inductively coupled plasma-mass spectrometry (ICP-MS) and graphite furnace atomic absorption spectrometry (GFAA). In addition to the high cost, the instruments are not always available. These methods are also not suitable for in field detection. This study developed a novel method to pre-concentrate the heavy metal elements in environmental samples by solid phase extraction. A large volume of water sample was extracted with a cartridge that packed with specific adsorbent, and then the metal elements were eluted with a small volume of solvent. The metal elements in the extracted samples can be analyzed by using HACH test kits or other rapid and less expensive methods. ICP-MS method was used to detect the metal elements concentrations and validate the newly developed method. The optimized experimental conditions and the method suitability for water samples analysis were studied.
