痕量碘的催化极谱法研究

A Study on the Catalytic Polarography of Trace Iodine

本文介绍在HAc-NaAc体系中,在OsO_4的催化作用下,用二次微分极谱法测定碘。方法的检出限可达5ppb。一定量的SO_4^(2-),Br^-,Cl^-等共存离子不干扰痕量碘的测定。本法用于天然水及食盐水中痕量碘的分析时,结果满意。

This paper presents a method of the determination of trace iodine by two order differential polarography with the catalytic action of OsO_4. The detection limit is 5 ppb. The results obtained in the determination of natural water and salt water are satisfactory.
