| 摘 要： | 在分析用纳氏试剂分光光度法测定空气中氨的各种误差因素,重点研究了由于吸收液受到空气的污染和吸收瓶对氨的吸附残留影响.得出结论是:在本地空气中氨的背景浓度水平为0.100 mg/m3时,吸收液污染和吸收瓶污染相对影响最高达到47%. |
| 关 键 词： | 空气 氨测定 吸收液污染 吸收瓶吸附残留 误差 |

| Abstract: | This paper makes a research on factors causing errors in determination of ammonia in air by spectrophotometry method with emphasis on the influences of absorbing liquid polluted by air and absorbed residual ammonia in absorbing bottles. The conclusion is that the relative influence of polluted absorbing liquid and absorbing bottle can be up to 47% when background concentration level of ammonia in local air is 0. 100mg/m^3. |
| Keywords: | air determination of ammonia polluted absorbing liquid absorbed residue in absorbing bottles error |
