| Abstract: | Disclosed in this paper is a process of recycling calcium phosphite from the waste residue,transforming it to sodium phosphite. Then take the concentrated NaH 2PO 3 as raw material and convert it into H 3PO 3 by electrodialysis. The practice process and optimal conditions are discussed in this paper,and as the result of the above process,plant will get more profits,not only in the economic,but also in the environmental aspects. |
