| Abstract: | A flame atomic absorption spectrometric(FAAS) method was developed for the simultaneous determination of 15 trace elements in cuttlebone.This method exhibited spike recoveries for 15 trace elements ranging from 96.5% to 108.7%,with RSDs of less than 2.8% and good accuracy and precision.A higher content of trace elements essential to the human body including Zn,Fe,Mn and Cu was detected in cuttlebone.Additionally,Pb,As and Cd were also detected. |
