摘要
建立了一种应用微波辅助萃取ICP—MS法测定土壤中有效硼的方法，该方法与NY／T148—1990和NY／T1121．8—2006（姜黄素比色法和甲亚胺比色法）相比，不仅操作简便快速、无污染，而且具有很好的准确度和精密度，其相对标准偏差（RSD）为3．5％，回收率为94．0％-107．3％，方法的检出限为1．13ng·g^-1。
A new method was established for the determination of soil available boron by using microwave assisted extraction and inductively coupled plasma mass spectrometry. Compared with NY/T148 - 1990 和 NY/T1121.8 - 2006, the recommended method was not only simple and rapid but also showed satisfying precision and accuracy. The relative standard deviation was 3.5%, and the recovery was 94.0% - 107.3%. The detection limit of the method was 1.13 ng·g^-1.
