摘要
通过碳酸钠-氧化锌混合试剂烧结碱溶样品,热水浸取、阳离子树脂进行交换,本文对土壤中碘含量的测定采用电感耦合等离子体质谱法(ICP-MS)。本方法通过对方法进行改进,解决了测试方法中条件苛刻、高低含量样品准确度低,实验结果稳定差等难题。本方法检出限、精密度及准确度均符合DZ/T 0258-2014《多目标区域地球化学调查规范》的技术指标要求。
Inductively coupled plasma mass spectrometry(ICP-MS)was used to determine the content of iodine in soil by using sodium carbonate and zinc oxide mixed reagent to sintered alkali soluble samples,soaking in hot water,and exchanging with cationic resin.By improving the method,this method solved the problems in the test method such as harsh conditions,low accuracy of high and low content samples,and poor stability of experimental results.The detection limit,precision and accuracy of this method met the technical requirements of DZ/T 0258-2014 Code for Multi-objective Regional Geochemical Investigation.
