The determination method of K, Na, Ca, Mg, Li, Sr and Mn in seawater by inductively coupled plasma atomic emission spectrometry (ICP-AES) was studied. The relative standard deviation is less than 3.35%, the relative error is less than 5.5%, and the recoveries of standard addition are 90% to 104.3%. The method is worthy of popularization from good linear correlation, high precision and accuracy and little interference.
