| Abstract: | A method for determination of mercury in toxicity characteristic leaching procedure extracts by microwave digestion and atomic fluorescence spectrometry was established.The optimal experimental conditions were investigated,including lamp current,the concentration of KBH4 and the flow of carrier gas.The mercury concentration was linear with fluorescene intensity in the range of 0.00-5.00 mg/L(r=0.9999),the detection limit was 0.032 mg/L.The relative standard deviations were 4.6% and 3.3%,respectively for two... |
