1,4-丁二醇中的39种金属元素的检测方法
Method for Detecting 39 Metals in 1,4-Butanediol
摘要: 建立了一种快速测定1,4-丁二醇中39种痕量金属元素的检测方法。使用电感耦合等离子体质谱检测有机物时，加入氧气，减少积碳，避免熄火。雾化室温度需设定为2℃，提供稳定的进样环境。1,4-丁二醇，黏稠且凝固点为20.1℃，与N-甲基吡咯烷酮混合后，混合物可以直接进样检测分析，从而减少预处理的检测误差。加标回收率在92.21%~105.96%之间，验证了方法的准确性。此方法检测1,4-丁二醇中的金属元素，具有高效、干扰小、污染少、灵敏度高的优点。
Abstract: A rapid detection method for 39 trace metal elements in 1,4-butanediol was established. When using inductively coupled plasma mass spectrometry (ICP-MS) to detect organic substances, oxygen is added to reduce carbon deposition and avoid flameout. The temperature of the nebulization chamber should be set at 2˚C to provide a stable sample introduction environment. 1,4-butanediol is viscous with a freezing point of 20.1˚C. After mixing it with N-methylpyrrolidone, the mixture can be directly injected for detection and analysis, thus reducing the detection errors caused by sample pretreatment. The recoveries of the spiked samples range from 92.21% to 105.96%, which verifies the accuracy of the method. This method for detecting metal elements in 1,4-butanediol has the advantages of high efficiency, less interference, low pollution, and high sensitivity.
