吸附剂Tenax-TA和活性炭对空气中苯的吸附性能比较

Comparison of Adsorptive Capacity of Benzene in Air between Tenax TA Adsorbent and Activated Carbon

分别采用吸附剂为Tenax-TA和活性炭的吸附管模拟现场采集室内环境空气,了解Tenax-TA和活性炭对空气中苯的吸附性能。当Tenax-TA吸附剂以0.5L/min的流量采集10L空气时,苯存在漏出现象。说明空气中苯的采集不宜用Tenax-TA吸附剂替代活性炭吸附剂。

Through simulated sampling of the ambient air indoors with adsorption tube filled with Tenax TA adsorbent and activated carbon respectively, adsorptive capacity of benzene in air from Tenax TA adsorbent or activated carbon could be found out, If 10 liter of air was sampled with Tenax TA adsorbent at a flow of 0.5L/min, benzene would leak out which indicated that Tenax TA adsorbent was not suitable for sampling of benzene in the air instead of activated carbon.
