| Abstract: | Objective:To discuss on testing the quantity of fluoride in tea leaves by ion chromatography.Methods:First,we tested the quantity of fluoride in tea leaves by separately using fluorinion selective electrode and the ion chromatography and then compared the results.Results:Both the fluorinion selective electrode and the ion chromatography gave out the same outcome.Ion chromatography,however,was better than fluorinion selective electrode approach in preciseness.Conclusion:Ion chromatography in fluoride testing can be handled more easily and is more sensitive,thus makes itself a better choice for the purpose. |
