The performance of electric field changes on the isoelectric and viscosity of the gelatin solution was investigated at different pH and supporting electrolyte in the electric field under the different conditions. It shows that after electrolysis one hour at 85mA DC current strength,NaCl and Na2SO4 are used as supporting electrolyte ,the isoelectric point of gelatin decreases by 0. 4 and 0. 2 when the gelatin at the anode side of cationic membrane,and both increases by 0. 2 when no cationic membrane exist. T...
