| 摘要: |
| 用化学吸收光度法(CAP)和热重-气相色谱联用法( TG-GC)测定了热分析逸出气中的氨。两种方法均简便、快捷和准确, 通常回收率在100±6%。比较了这些方法的使用范围。 |

| Abstract: |
| This paper presents the determination methods of the evolved NH3 from thermal analysis by chemical absorption-photometry (CAP) and combined thermogravimetry-gas chromatography (TG-GC).The two methods are simple, rapid and exact. A recovery within 100±6% is generally obtained. The applicable range of these methods is compared. |
