摘要
本文讨论了用有机滤膜采集空气中TSP后,样品经过蒸馏水浸泡,超声波震荡、微孔滤膜过滤、电渗析予处理等前处理后,离子色谱法快速分析样品中的硫酸根,氯离子、氟离子及硝酸根的含量,依此计算出单位体积内上述各离子浓度水平,从而找出包头市区在采暖及非采暖季节大气TSP中硫酸根等阴离子的含量水平和分布特征。
The paper discussed the content level and distribution character of four anions(SO 2- 4,etc)in the air particles of Bao Tou urban districts.First of all,the total suspending paarticles(TSP)were collected by organic filtering membrane.Next,they were pre-treated by technical measures including dipping into distillation water、supersonic-vibrating、micro-porous filtering membrance and electrodialysis.Then,the contents of SO -2 4、CL -1 、F -1 and NO -1 3 in the samples were analysed quickly by ion chromatography,and per unit concentration level of above anions were calculated respectively.Finally,the content level and distribution character of four anions in the air TSP of Bao Tou urban districts were found out in both heating and non-heating season.
