Abstract:The tetraethyl lead was extracted from water with Trichloromethane.The extract was detected by Graphite Furnace Atomic Absorption Spectromettry method. The detection limit was 1.3×10~(-5)mg/L. The average recoveries were between 90.4%~108% . The method is effective, fast and accurate.
Keywords:The tetraethyl lead  Water  Trichloromethane  Extract  Graphite Furnace Atomic Absorption Spectromettry method
