摘要
采用氧弹燃烧-离子色谱法测定助焊剂中的碘.使用NaOH-抗坏血酸(AA)复合成分作为吸收液有效成分,可将氧弹燃烧对碘的吸收率达到90%左右,并且能有效解决以单一AA成分作为吸收液有效成分氧弹燃烧后,样品在进行离子色谱测试时基线过高而不能准确识别碘的问题.实现碘含量在50～1000 μg范围内助焊剂样品碘的高效吸收以及准确测定.方法安全,环保,操作便捷,在助焊剂中碘含量的准确测定方面可发挥重要作用.
Abstract
Oxygen bomb combustion-ion chromatography method was used to determine iodine in soldering flux.Using NaOH-ascorbic acid(AA)composite as the active ingredient in the absorption solution is capable of increasing the absorption rate of iodine by about 90%by oxygen bomb combustion method.Comparing with using only AA as the active ingredient in the absorption solution,it can effectively solve the problem of high baseline and inaccurate identification of iodine in ion chromatography-testing after oxygen bomb combustion.The proposed method possesses ability to efficiently absorb and accurately detect iodine content in tin flux samples within the range of 50-1000 μg of iodine content.The method is safe,environmentally friendly,easy to operate,and can play an important role in the accurate determination of iodine content in flux.
