Abstract: A technique, recently described1 for recovery of Eastman Color developers, has been modified. In the new method, developer is passed through the ion-exchange column only as long as sodium bromide is completely removed. The effluent solution is reconstituted to replenisher status by the addition of untreated overflow developer, developing agent and sodium sulfite. The advantages of this technique are: increased life of the resin, elimination of several chemical analyses and reduction in operating time by half.
