| Abstract: | Objective: To establish a simultaneous determination of Cl-,Br-,NO3-,SO42-,PO43- content of gardenia by ion chromatography. Method: The ICS-900 ion chromatography and IonPac AS11-HC inorganic anion exchange chromatography column,KOH gradient elution and conductivity detection were adapted to assay the five kinds of inorganic anion. Result: Cl-,Br-,NO3-,SO42-,PO43- were good in linearity. Samples recovery were between 97%-102%. The content of Cl-,Br-,NO3-,SO42-,PO43- were 0.084%,0.063%,0.070%,0.30% and 0.12%. Conclusion: The method is sensitive,accurate and operational,provided a simple and quickly method to assay the content of Cl-,Br-,NO3-,SO42-,PO43- in gardenia. |
