ABSTRACT:
A process for purifying contaminated aqueous solutions without using ion exchange resins or organic solvents is provided. The process comprises contacting an aqueous solution with a non-polymeric getter compound in a dispersed state to remove dissolved contaminants or recover dissolved valuable materials. Suitable getter compounds having pendant long chain hydrocarbon radicals and complexing moieties are disclosed. The process is highly efficient and effective for removing a wide variety of dissolved contaminants such as metal ions, non-metal ions and dissolved organic contaminants such as dyes.
