Abstract：A method was developed to determine sulfur and boron in salt Lake brine and salt products using inductively coupled plasma atomic emission spectrometry (ICP-AES). The samples were determined after simply diluting with water. The detection-limitation of element was 0.04～0.38 mg/L; the recovery was between 97.56% and 102.4%; and the relative standard deviation was less than 3.5%. This method was simply and rapid with great precision and high accuracy, which could be used to analyze S and B in salt Lake brine and salt products.

Key words：ICP-AES; salt lake brine; salt products; sulfur; boron
