Breakthrough behavior of sulphur mustard vapor on activated carbon

Abstract

Active carbon (surface area, 1250 m²/g) was used to study vapor breakthrough behavior of sulphur mustard (2, 2’- dichlorodiethyl sulphide). Effect of length of carbon bed on vapor breakthrough time has been examined. Rate constant (kv) is found to increase while kinetic saturation capacity (We) is invariable with increase in airflow rate. Both kv and Wℯ decrease with the increase of temperature, however, no significant effect on Wℯ and kv was observed due to concentration change (0.3- 0.6 mg/l). Values of kinetic saturation capacity are used to predict service lives/breakthrough times of carbon beds (when used in filtration systems).
