| Abstract: | The paper studied rapid determination method of familiar eleetropositive ion in water supply sample with effective capillary eleetrophoresis. The result showed seven kinds ion including K^＋、Na^＋、Li^＋、Ca^2＋、Mg^2＋、Ba^2＋、Sr^2＋ were entirely separated within 8 minutes, recovery ratio was from 98.0% to 103.3%. Standard deviation kurtosis area and migratory time were respectively 3.2% and 1.1%, fidelity was good, and this method had good determination sensitivity. |
