Determination of 10 Elements including Silicon, Iron and Aluminum in Rock, Stream Sediment and Soil Samples by ICP-AES with Lithium Metaborate Fusion and Ultrasonic Extraction

A method for the determination of 10 elements, including Si, Al, Fe, Ca, Mg, K, Na, P, Mn and Ti in rock, stream sediment and soil samples by inductively coupled plasma-atomic emission spectrometry (ICP-AES) was reported. Samples were decomposed with lithium metaborate and dissolved with ultrasonic extraction. The sample solution was then determined by ICP-AES. The method has been applied to the determination of these 10 elements in National Standard Reference Materials with satisfactory results. The method is suitable for quantitative analysis of multielements in rock, stream sediment and soil samples.
