Abstract

Various test conditions and effect factors for the determination of selenium by flow injection-hydride generation-atomic absorption spectrometry were discussed and a method for the determination of selenium in tricholoma giganteum has been developed. The linear range for selenium is 0-50 microg x L(-1). The relative standard deviation is less than 3% and the recovery is 96%-105%. This method is simple, rapid and has been applied to the determination of selenium in tricholoma giganteum with satisfactory results.

摘要

探讨了流动注射-氢化物发生-原子吸收光谱法测定硒的各种试验条件和影响因素，并建立了测定巨大口蘑中硒的方法。硒的线性范围为0 - 50μg·L⁻¹。相对标准偏差小于3%，回收率为96% - 105%。该方法简便、快速，已应用于巨大口蘑中硒的测定，结果令人满意。
