| Abstract: | A sensitive method for the determination of trace mercury in tea leaves was developed by using the intermittent flow hydride generation atomic fluorescence spectrometry. Under the optimized conditions, the detection limit was 0.03 ng/mL for mercury. The method has been successfully applied to the determination of mercury in tea leaves sample with the recoveries within the range of 95 % - 103 %. |
