摘　　要：长期以来都是通过测定四氯化碳荷量或吸苯率，来评价用于气相吸附活性炭的吸附性能。由于四氯化碳是剧毒试剂，苯是致癌物质，所以本文改用环己烷作为吸附质，通过测定各种活性炭对环己烷的吸附等温线，详细讨论了环己烷荷量作为评价活性炭吸附性能的条件。并介绍了快速测定活性炭对环己烷的吸附荷量的迎头色谱穿透曲线法。As carbon tetrachloride is a severe toxicant and benzene is a chemical carcinogen, the author substituted cyclohexane for carbon tetrachloride and benzene as a testing substance for gas phase activated carbon. The adsoption isotherms of cyclohexane on various activated carbons have been determined and conditions for testing the adsorption activity at different relative pressure of cyclohexane loading are discussed in detail. The equipments,experimental conditions and operational procedures are introduced.
