ABSTRACT:
A waste solution containing heavy metals tightly bound by complexing agents such as EDTA, NTA, and thiosulfate is treated by contacting the solution with a mixture of peroxide and ozone to oxidize and destroy the complexing agents thereby facilitating separation and recovery of the heavy metals and reducing pollution of streams by the heavy metals.
