| Abstract: | This paper presents a method for the determination of manganese in the organism of the Chinese herbal medicine of the Polygonum multiflorum. Manganese was complexes, extracted and determined by FAAS. The opimum condition of experiment was studied. The accuracy and the detection limit were 7.6 and 8.4 ng.mL-1 respectively. The Mn was determined in range of 0.00-2.00 micrograms.mL-1. The relative standard deviation was 1.77%. |
| Keywords: | FAAS Mn Polgonum multiflorum |
