摘要
建立了一种应用微波辅助萃取-电感耦合等离子体质谱法检测食品中的硼砂的方法。以0.1 mol/L氨水来消除硼的记忆效应。硼含量在0～2.0μg/mL范围内线性关系良好,R=1.0000。硼砂检测限为2.0 ng/mL(σ=3),RSD小于5%,方法回收率为95.2%～103.4%。该法与GB/T21918-2008中的三种检测方法相比,具有操作简单、快速、试剂污染少的特点。可作为食品中硼砂含量的检测方法之一。
The establishment of a microwave-assisted extraction - inductively coupled plasma mass spectrometry detection of food in the borax method. To 0.1 moL / L ammonia to eliminate the memory effect of boron. Boron content of （0 - 2.0） μg/mL range a good linear relationship, R = 1.0000. Borax detection limit of 2.0ng / mL （ σ = 3 ）, RSD less than 5%, and 95.2% recoveries of 103.4%. The law was compled with GB/T 21918-2008 in the three test methods, simple, rapid, reagent pollution characteristics. Boric acid as a food in one of the detection method.
