The Principle and Application of Three-Wavelength Spectrophotometry

Guo Nairong Luo Qingyao Chen Zhenhua Zeng Yun′e (Department of Chemistry,Wuhan University)  
It is more advantageous to use this method than dual-wavelength spectrophotometry in accuracy in the presence of interferent. The reasonable isoabsorption points could not be found out in the absorption band of the latter. We have utilized this method to determine Sc and RE in their compounds. The colour reagent is amino-c acid chlorophosphonazo synthesized in our laboratory. The relative error is in the range of 10%.
