ABSTRACT:
Metal chelates in solution are decomposed more effectively and completely by ozonation when magnesium hydroxide is added to the chelate solution prior to ozonation. The process is particularly applicable to waste streams from which it is desired to recover metals to avoid contamination of the environment and/or reuse them.
