摘要
用悬浮液进样-火焰原子吸收光谱法测定湘玉竹中铜,样品经烘干、研磨、过筛配制琼脂悬浮液,直接喷人空气.乙炔火焰测定,本法测定加标回收率为97.8%,99.7%.方法的HSD小于2,5%(n=6),检测限为0.0038μg·mL^-1.
Cu in polygonatum odoratum (MiLL) druce is determined by FAAS adopting suspension sample intruction. Samples are dried, sieved and made into agar suspension to be injected into air-acetylene flame for determination, Recovery rate of standard addition is 97.8% - 99.7%. RSD is less than 2.5% and the detection limit is 0.0038(g/mL.
