微波溶样-ICP-AES法测定淮南田家庵电厂粉煤灰中18种元素

method for the determination of multiplex elements in powder fly ash from Huai Nan tian jia an Power Plan by inductively coupled plasma atomic emission spectrometry (ICP-AES) has been presented .The mutual interference of the thirteen elements and the treatment of the sample are studied in details .The relative standard deviations (RSD) are less than 3% and the recoveries of most elements are in the range of 96.0%~103.0%. This method was simple convenient、quick and accurate. The method can be used for the quality control of trace elements in powder fly ash and for develop and making use of powder fly ash to provide science the basis further.
