摘　　要：本文对中草药何首乌中的锰 ,以络合萃取、分离富集后 ,用火焰原子吸收光度法直接测定有机相 ;并对测定锰的最佳实验条件等进行了试验。该方法测定锰的灵敏度为 7 6ng·mL- 1 ,检出限 (K =3) 8 4ng·mL- 1 ,线性范围 0 0 0～ 2 0 0 μg·mL- 1 ,相对标准偏差 1 77%。This paper presents a method for the determination of manganese in the organism of the Chinese herbal medicine of the polgonum multiflorum. Manganese was complexes, extracted and determined by FAAS. The opinum 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 mug (.) mL (-1). The relative standard deviation was 1.77 %.
