실험 절차

The bipolar membrane prepared in this manner was used for the electrodialysis as described in Example 2, the apparatus being shown in FIG. 2. Electrodialysis was carried out for 10 hours at room temperature and at a current density of 2.9 A/cm2. 200 parts of an aqueous 0.25 molar solution of disodium naphthalene-1,5-disulfonate were used in compartment (9), and 100 parts of 0.5% strength sodium hydroxide solution were employed in compartment (8). 1937 parts of a 0.24 molar solution of monosodium naphthalene-1,5-disulfonate (0.02 mole/kg of the disodium salt, current efficiency 50%) were obtained in compartment (9), and about 1000 parts of 2.2% strength Sodium hydroxide solution were obtained in compartment (8).
