微分脉冲催化极谱法测定富硒大米中的痕量硒

Determination of Trace Selenium in Selenium-Rich Rice by the Method of Differential Pulse Catalytic Polarography

采用美国273A型电化学分析系统,根据SeSO32--KIO3氧化还原反应原理,用微分脉冲催化极谱法测定了富硒大米中的痕量硒。

This method was based on the SeSO32--KIO3 principle of oxidation and reduction.Through using 273A type Electric Chemical Analytic System(Made in America,1992),the trace selenium of selenium-rich rice was determined by the method of differential pulse catalytic polarography.
