ABSTRACT:
Selenium exists in oil refinery stripped sour water as selenocyanate and can be effectively removed using an acrylic, strong base, anion exchange column or stannous chloride. The acrylic, strong base, anion exchange column can also be employed to remove arsenic, iron, and vanadium from an aqueous fluid.
