铬鞣剂中微量六价铬测定方法的研究

Study on the method of trace Cr(Ⅵ) determination in chrome tanning agents

研究了铬鞣剂中可能存在的微量六价铬的分离和测定方法。该方法灵敏度高 ,摩尔吸光系数为 1.6×10 6,干扰少 ,可测定高浓度 Cr( )中微量的 Cr( )

The method for the separation and determination of trace Cr(Ⅵ) in chrome tanning agents is researched. This method is highly sensitive and less interference, Molar adsorption coeffition is 1.6×10 6,trace Cr(Ⅵ) can be separated and determined in high concentration Cr(Ⅲ)
