固定污染源排气中氟化物监测方法研究

Study on Monitoring Method of Fluoride Discharged from the Fixed-Source Pollution

采用直接蒸镏法对固定污染源中固态氟化物样品进行处理,使用离子色谱或离子选择电极对样品进行测定,结果表明:其测定范围、精密度、准确度,均能满足环境监测的要求。

Sample of solid state fluoride from the fixed-source pollution of electrolyzing aluminium industry was treated by the method of direct distillation firstly, and then it was monitored by iron chromatography or iron-selection elective electrode analysis. The monitoring results show that the monitoring range and precision of the method can meet the requirement of environmental monitoring.
