ABSTRACT:
Dissolved molecules of nonionogenic, hydrophobic, pesticidal, organic compounds are removed from streams by passing them through a bed or mass of macroreticular adsorbent resin. The preferred resins are aromatic in character, being composed of 80 to 90 weight percent of divinylbenzene, and from 20 to 10 weight percent of ethylvinylbenzene, and have a specific surface area of 800 square meters per gram .+-. 20%, a porosity of 50% .+-. 10% by volume, and an average pore diameter of 50 Angstrom Units .+-. 20%.
