摘要: Electrodialysis with two different configurations was used for the recovery of NaOH from waste stream a MEROX tower. For this purpose, effects cell applied voltage and initial Na+ concentration in feed solution on current efficiency were studied. Results showed that improved by increasing concentration. Also, had efficiency. A about 70% 98% three-compartment at 15 volts method can be considered as promising one
