| Abstract: | The absorbency of carmine and apple green mixed system was determined in the range of 300~600 nm wavelength,and then the support vector regression(SVR)methods was used for modeling.A SVR-spectrophotometry method was established to simultaneously determine carmine and apple green,which applied to a simulated sample afterward.The results showed that the average recovery of carmine and apple green were 97.645% and 100.895%.The results are satisfactory. |
