| Abstract: | An IC method for separation and quantitative analysis of ethephon 40% SL was developed.[Methods]The method was based on ICS separation under the condition of gradient eluent with KOH solution by using of the IonPac AS11-HC analytical column and conductivity detector.[Results]The result showed that the linear correlation coefficient was 0.9998,the standard deviation was 0.19,the variation coefficient was 0.45% and average recovery was 99.71%.[Conclusions]The method was simple,rapid,accurate,safe and suitable... |
