Abstract
Solid sorbents such as activated carbon and ion exchange resins are ballasted with finely divided particles of a non-corrosive, magnetic iron-chromium alloy to increase their effective specific gravity and to render them recoverable by magnetic means. The sorbents are used to selectively extract one or more constituents contained in a liquid as by contacting in a multi-stage fluidized bed.
