The removal of organic matter with a weakly basic macroreticular ion-exchange resin. A case history.
Natural waters containing organic pollutants have a strong tendency to foul anionic exchange resins irremediably. The use of various types of scavenging resins is discussed and results are given on trials carried out at a chemical plant. The conclusion is drawn that a proper analysis of organic matter present in water cannot be made and that consequently it is difficult to determine which types of scavengers are the most suitable. The paper suggests a principle of calculating weakly basic macroreticular resins into the flow system so as to function both as a scavenger and a weakly basic ion-exchange resin.
