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 getter compound and a non-polymeric carrier compound in a dispersed state to remove dissolved contaminants or recover dissolved valuable materials. Suitable carrier compounds having pendant long chain hydrocarbon radicals and hydrophilic 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.
