| Abstract: | NaHSO_3 waste liquor is generated by bipolar membrane electrodialysis make up by one bipolar membrane and two pieces of carbon exchange membranes.The regeneration rates are above 90%.Some factors are studies such as the current density,the bulk concentration,electrode rinse concentration and acidity,compartment flux,and Na_2SO_4 content that effects regeneration process.The current efficiency and the energy consumption of the process are studied,which can give some references for industrial application. |
