摘要
目前,婴幼儿配方奶粉是非母乳喂养婴幼儿的主要食品,也是碘摄入的主要来源,由于碘的含量较低且过量摄入对婴儿生长发育不利,因此准确高效地测定碘的含量显得十分重要。国内外对碘含量检测的方法主要有气相色谱法、电感耦合等离子体质谱法(ICP-MS)、离子色谱法等。文章总结了这几类方法的样品前处理及检测手段,并通过分析得出,离子色谱法是检测婴幼儿配方奶粉中碘含量比较理想的方法。
At present, infant formula milk powder is the main food of non-breastfeeding infants, but also the main source of iodine intake, iodine content is low, so accurate and efficient determination of iodine content is very important. At home and abroad on iodide detection methods and testing standards are gas chromatography, inductively coupled plasma mass spectrometry (ICP-MS), ion chromatography. Through several methods of sample pretreatment and detection means analysis, the results are obtained, ion chromatography is an ideal method for the detection of infant formula milk powder.
