标准编号：ISO 6491:1998

中文名称：动物饲料.磷含量的测定.分光光度法

英文名称：Animal feeding stuffs — Determination of phosphorus content — Spectrometric method

发布日期：1998-12

标准范围

本国际标准规定了测定土壤中磷含量的光谱测定方法动物饲料。本方法适用于磷含量低于50g/kg的动物饲料。尤其是适用于低磷产品的分析。对于磷含量较高的产品，建议使用重量分析法，例如使用喹啉磷钼酸盐。

This International Standard specifies a spectrometric method for the determination of the phosphorus content ofanimal feeding stuffs.The method is applicable to animal feeding stuffs with a phosphorus content less than 50 g/kg. It is particularlyappropriate for the analysis of products with low phosphorus content. For products with higher phosphorus content,application of a gravimetric method is advised, using for instance quinoline phosphomolybdate.
