| Abstract: | A method for the determination of trace in lotus samples by hydride generation-atomic fluorescence spectrometry was researched. The sample was digested with HNO3-HCIO4 mixed acid. Under the selected experimental conditions, the method detection limit was 0.54 μg / L, RSD was less than 2.16 %, the recovery rate was 95 % - 102.3 %. |
