用能量色散型X荧光法测定超高磷铸铁中的磷

Determination of P in Superhigh P Cast Iron by EDXRF

本文研制的超高磷铸铁标样成分均匀、定值准确、含量范围宽。应用能量色散型Ｘ荧光光谱分析和粉未压片法对样品中的磷进行了测定。在测定过程中改进了粉未压片工艺和Ｌｕｃａｓ－Ｔｏｏｔｈ强度校正软件。本方法快速简便，分析结果令人满意。

In this peper preparation of standard samples of superhigh P cast iron has been studied and P in the samples has been determined by EDXRF and powder compacting.In the process the procedure of powder compacting and the software of a multifunctional Lucas Tooth intenstity correction have been developed.The method is rapid and simple.Analytical results were satisfactory.
