摘　　要：建立火焰原子吸收分光光度法测定地新糠糊中氧化锌的含量。对样品进行高温灰化处理，采用火焰原子吸收分光光度法。结果锌在0．4～2．4μg．ml^-1范围内有良好的线性关系（r=0．9998）；平均回收率为101．0%，RSD为0．95%（n=9）。本法准确、快速，可作为测定地新糠糊中氧化锌含量的方法。A flame atomic absorption spectrometry （FAAS） method for the determination of zinc in Dixinkang Paste was established. The samples were treated by high temperature ashing and analyzed by FAAS. A good linearity was obtained when the content of zinc was within the range of 0.4-2.4μg · ml^-1 （r=0.9998）. The average recovery rate was 101.0% and RSD was 0.95% （n=9）. The method was accurate and rapid. It could be used in the determination of zinc in Dixinkanghu Paste.
