Abstract
An electrolytic method and apparatus for treating a solution sample allowing for the accurate and substantially real-time and on-line analysis of trace contaminants in the solution sample. The method of the present invention includes two stages. The solution sample is electrolyzed during a first stage to decompose the matrix, thereby substantially neutralizing the matrix, while during a second stage deposited or precipitated metals are recovered and/or stabilized in solution. An apparatus for carrying out the method is also disclosed.
