抄録

A new technique of powdering acrylic fiber was studied for X-ray spectrometry. In the technique developed here, fiber was cut and milled by shaking with quartz fragments. It was applied to the determination of tin in acrylic fiber in the range of (0.10.5) weight percent. The ability of powdering and reproducibility of the measured X-ray intensity depended on the weight ratio of fiber to quartz and mixing time. The best results were obtained when mixing 2.00 g of fiber with 4.50 g of quartz for 60 min. The powder was pressed under the load of 10 ton/cm2. Tin was determined by the dissolution technique at the same time and the deviation of the two different determinations was (0.010.06)%. This technique is applicable to analyze the other elements in fibers by X-ray spectrometry.
