摘    要:采用了四种材质即聚乙烯、聚氯乙烯、硬质玻璃和金属加特氟龙涂层采样器,在同一地点、同一时间采集同一场降雨,所获得的样品经过中速定量滤纸过滤,在相同实验条件下进行离子色谱分析。结果表明:聚氯乙烯材质采样器采集的降水样品pH值降低,电导率升高,且使其中的氯离子浓度产生显著性差异,其余材质采样器所采集的降水样品中的各阴离子浓度无显著性差异;四种材质采样器所采样的降水样品中的各阳离子浓度也无显著性差异。

关 键 词:材质  采样器  降水  离子组分  显著性差异

Abstract:The wet deposition sample was collected by using sampler made by four kinds of materials with polyethylene,polyvinyl chloride(PVC),hard glass,coating of polyfluortetraethylene in the same site and time,and filtered by using middle speed,and analyzed with IC in the same experiment condition.The results showed:pH of the sample collected by polyethylene sampler is decreasing,its conductivity is rising,and Cl - concentration of this sample has remarkable difference compared with other three kinds of samples.The anion concentration in sample collected by other three kinds of material samplers has no remarkable deviation.The cation concentration of sample collected by four kinds of material samplers has also no remarkable deviation.
Keywords:material  sampler  wet deposition  ion component  remarkable deviation
