摘要
研究了不经分离，直接测定多金属鞣革液中稀土含量的双波长分光光度法．用偶氮胂Ⅲ作显色剂，ＥＤＴＡ掩蔽干扰离子，所得结果重现性及回收率均良好．本法简便，准确可靠。
The study on determining the rear earth elements in the multiplmetal tanning solution with dual wavelength spectrophotometry can be done without sample separation.With arsenazo Ⅲ as color reagent and EDTA as making agent,the reappearance,accuracy,and recovery are good and the method is easy.
