【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1.13 ng.g-1。更多还原

【Abstract】 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.更多还原
