| 中文摘要: |
| 通过比对6种吸附剂对氯苯类化合物的吸附性能，同时考察不同废气温度、湿度条件下活性炭对氯苯类化合物的吸附-解吸性能，表明活性炭对氯苯类化合物的吸附性能及在二硫化碳介质中的解吸效能与标准规定的GDX系列无显著性差异。将活性炭管吸附采样用于监测某化工企业厂界无组织排放废气中的氯苯类化合物，结果1,4-二氯苯和1,2,4,5-四氯苯检出。 |
| 英文摘要: |
| The adsorb properties of activated carbon, silica gel, XAD 2 resin, Tenax, florisil，GDX and other commercial adsorbents to chlorobenzenes were studied by comparison. At the same time, the adsorption and desorption performance of activated carbon to chlorobenzenes adsorption were investigated at different temperature and humidity. Results showed that activated carbon had the same adsorption efficiency and stable desorption performance with GDX series in carbon disulfide medium. Applying activated carbon absorbent to collect chlorobenzenes in fugitive emission from a chemical industry, 1,4 dichlorobenzene and 1,2,4,5 tetrachlorobenzene were detected. |
