| 摘 要： | 通过测定苯回收率的方法探讨了使用Tenax-TA吸附剂检测室内空气中苯浓度的影响因素,如样品浓度、Tenax-TA试剂重量、采样温度、采样流速、采样体积等.试验结果表明,在一定浓度范围内,样品浓度不影响苯回收率;采样流速对苯回收率影响较小;而Tenax-TA试剂重量、采样温度和采样体积对苯回收率影响显著.

| Abstract: | Based on testing benzene reclaim ratio,the influence factors of detecting benzene in the indoor air using Tenax-TA absorption was discussed,such as benzene concentration,weight of Tenax-TA reagent,indoor temperature,velocity,air volume and so on.The experiment results indicated that benzene concentration had no effect on the recovery rate of benzene when the benzene concentration was low,the recovery rate of benzene affected by the velocity is slightly,but the weight of Tenax-TA,indoor temperature and air v... |
