Abstract: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.
Keywords:inductively coupled plasma-atomic emission spectrometry  lithium metaborate  ultrasonic extraction  graphite crucible  simultaneous determination of multi-elements  rock  steam sediment  soil
