The feasibility of electrodialysis for the desalination of iron dextran and the design of electrodialysis devices were studied.The effect of electrodialysis desalination on produce quality,and the economic comparison between electrodialysis and ethanol desalination,were discussed.
The determination of phosphonomethyliminodiacetic acid by external stardand method was described.A solution of 0.005mol· L~(-1)KH_2PO_4(pH 2.0) was used as the mobile phase,SAX column was used and the UV-detection at 195nm was applied.The correlatiom coefficient for both compounds were respectively found to be 0.9996 and 0.9989.The stardand deviation were respectively 0.035 and 0.098. Recoveries were respectively in the range 98.5%～101.5% and 97.8%～102.5%.
Several kinds of novel electrodialysis were summarized.The applications of electrodialysis in water treatment,food industry and chemical engineering was briefly introduced.
