Abstract

This article focuses on iodine determination by microwave plasma torch atomic emission spectrometry (MPT-AES) coupled with online preconcentration vapor generation method. A new desolvation device, multistrand Nafion dryer, was used as the substitute for condenser desolvation system. Some experimental conditions, such as preconcentration time, acidity of sample solution, rinsing solution acidity and dynamic linear range were investigated and optimized. The new desolvation system eliminates the problem of decreasing emission intensity of I(I) 206.238 nm line with the increase of working time on a conventional condenser desolvation system, thus greatly improving the reproducibility.

微波等离子体炬原子发射光谱仪-在线预浓缩蒸汽生成技术测定碘

本文研究了微波等离子体炬原子发射光谱法(MPT-AES) -在线预浓缩蒸汽生成法测定碘的方法。采用了一种新型的脱溶装置——多股Nafion干燥器来代替冷凝器脱溶系统。考察并优化了预富集时间、样品溶液酸度、漂洗溶液酸度及动态线性范围等实验条件。该系统解决了传统聚光镜脱溶系统中I(I) 206.238 nm线发光强度随工作时间增加而降低的问题，从而大大提高了重现性。
