摘要: 制备了7种树脂试剂。采用空气瓶预分解徽量有机物,配合树脂试剂法鉴定氮、硫和卤素。检出限(μg)分别为:NO3-0.023,SO42-1.2,F-0.03,Cl-2.1,Br-0.05及I-0.9。并研究了氮的"假检出"问题。

Abstract: Seven kinds of resin reagents have been prepared. These resin reagents have been successfully applied to the detection of nitrogen, sulfur and halogen in organic compounds which were previously decomposed by means of air(oxygen) flask method. The detection limits(μg) are NO3- 0. 023, SO42- 1. 2, F- 0. 03, Cl- 2.1, Br- 0. 05 and I- 0.9 respectively. The false test for nitrogen has been studied.

Key words: Air flask, Resin reagent, Detection of organic elements
