摘要
利用混合纤维素滤膜可溶于丙酮的特性,将超低含量(<0.5%)石棉材料中的游离石棉进行富集,从而准确、快速地对石棉纤维进行定性分析,避免了由于纤维含量低、取样不均匀、样品基质的影响导致石棉纤维的漏判和误判。
The free asbestos in asbestos materials with ultra-low content (〈0.5%)was enriched by the acetone-soluble properties of the mixed cellulose filters.It can extremely improve the accuracy of the qualitative and protect the sample from falsely determination, which caused by the low content of fibers, sampling inhomogeneonsty and complex sample matrix.
