| Abstract: | The ion chromatography method is established in this experiment to determine the anions F-.SO2-4 in the plant samples.Firstly,the samples are melted by mixed flux of Na2CO3-ZnO(3+2),and extract with the second boiling water,secondly,the solutions are treated by cation exchange resin,and then separate and determine the anions from plant samples by ion chromatography,after detecting by suppressed conductivity.Verified by the national plant standard reference,this method is of preferable accuracy and repeatabi... |
