X射线衍射法测定滑石粉中石棉成分

Detection of Asbestos in TALC Using X-ray Diffraction

使用X射线衍射法,通过石棉的2θ特征峰进行判断,分析滑石粉中可能存在的石棉成分。结果表明,样品中不含温石棉、铁石棉和青石棉,并对温石棉和绿泥石进行了有效区分。方法快速,灵敏,可有效用于滑石粉中石棉的测定。

Asbestos that possibly exists in TALC was verified based on the characteristic 20 peak of asbestos using X-ray diffraction technique. The results show that the tested samples do not contain ehrysotile B Canadian,Amosite asbestos and crocidolite Asbestos. In addition, the effective compositions of chrysotile B Canadian and chlorite were analyzed. The method is rapid, sensitive and can be efficiently used for the determination of asbestos in TALC.
