Abstract

The isolation and determination of very small quantities of materials in complex mixtures is a major problem for analytical chemists in many fields. Historically [cf. R.P. Maickel, #A-1 -Ed.], solvent extraction has been the principal technique used for sample preparation; now solid-phase materials such as bonded silicas and small-particle resins are becoming accepted as convenient and efficient extraction sorbents. Two types of these solid-phase materials are now discussed and compared: lipophilic sorbents such as C-l8 bonded silica, and anion-exchange resins.
