| Abstract: | The method to determine K, Na, Ca and Mg in the surface water by continuum source atomic absorption spectrometry has been developed. The paper mainly discusses the influencing factors such as cesium salts, lantha- num salts, SO2- and A13 ＋ ; and the curve line, detection limit, precision and accuracy of measurement with differ- ent concentration range by principal or secondary sensitive line. The results shows that it is a simple, time-saving and very practical method. |
