Abstract:

An analytical method for determining twenty metal elements in water by ICP-AES simultaneously is reported. Under the optimum analytical conditions, the respective detection limit of the method is determined, the recoveries are between 90% to 110%, and the relative standard deviation is less than 5%. The method is accurate and rapid.

Key words: inductively coupled plasm atomic emission spectrometry, water qualit, metal elements
