摘要
介绍一种聚吡咯碳糊电极,采用反向差分脉冲伏安法测定精制食盐中的碘,结果令人满意,实验数据表明该电极有使用方便,响应灵敏度高,测定线性范围宽,重现性好的特点。可用于加碘食盐及含碘食品的测量。
This paper studies determination of trace iodine in salt by use of reverse differential pulse voltammetry with a pyrrole paste carbonelectrode.This method has many advantages,such as convenient operation,high sensitivity,wide linear range and satisfactory repeatable results.
