对不同产地海参中总锗的含量进行测定．采用灰化法对样品进行处理，以 CTMAB 为增溶剂，明胶为稳定剂，苯芴酮为显色剂，在酸性条件下进行显色，利用分光光度法测定海参中锗的含量．该体系在503 nm处有最大吸收峰，回归方程为A ＝1．0925 C＋0．16815，线性范围为0．072～0．504μg/mL， r＝0．9978，方法的回收率为98．54％～99．30％，RSD为1．9％．本方法样品处理简单，准确度高，可用于海参中锗的含量测定．

To determine the content of Germanium in Sea Cucumbers ,the samples were treated by ashing meth-od,and Germanium was colored with Phenylfluorone in the acidified solution with CTMAB as solubilization a -gent and gelatine as stabilizer ,and the content of Germanium was determined by Spectrophotometry .The maxi-mum absorption of association complex was at 503 nm.Regression equation was A=1.092 5C +0.168 15,the linear range 0.072~0.504 μg/mL,r=0.997 8,the recovery 98.88%,RSD 1.9%.This method was simple, accurate ,and could be used to determine the content of Germanium in Sea Cucumbers .
