Abstract |
When aluminum electrodes are used, the aluminum goes into solution at the anode and produces aqueous
aluminum species and hydrogen gas is released at the cathode. Coagulation with aluminum salts occurs at a wide range of
pH due to different mechanisms. In the EC process, the pH of the coagulation cell increases with liberation of H2 at the
cathode. This increase is mainly dependent on the current for all cases. When pH<4, aluminum remains in the form of Al3+,
and no precipitation occurs, so the fluoride concentration cannot be reduced. When 4 |
