低压过渡金属离子色谱仪分析铬—铝—锆鞣液中Zr含量

Analysis of the Content of Zr in Chrominum-Aluminium-Zcreonium Tanning Liquor by Low Pressure Tranition Meatal Lon Chometograph

本文介绍了用低压离子色谱仪分析铬—铝—锆鞣液中的锆含量.方法线性关系好,相关系数达0.9996,精密度高,变异系数为0.50%,灵敏度,检测限达1×10^(-6)mol/LZr,回收率在97.5～100%之间.分析速度快,2～3分钟可完成一次分析,准确度可满足制革生产过程中Zr含量的分析要求.

This paper describes the analysis of the content of Zr in Chrominum-Alu-mini-um-Zirconium tanning liquor by method of low pressure ion chrematogrophy. The advantages are; excellent linear relationship with the correlation coefficient 0. 9996 ;precise accuracy with the variation coefficient only.0. 50%; high sensitivity with the detection limit 1x10^6 molZr/L;recovery ratio between 97. 5-100% ;quick performance , eg. only two or three minutes for each analysis; outstanding accuracy being satisfied of the requirement of Zr content analysis in leather making processing .
