摘要:
The present invention relates to a method of treating polyaluminium compounds comprising contacting at least one polyaluminium compound in an aqueous solution with an anion exchange material capable of accepting anions or anionic groups and donating hydroxyl ions for a time necessary to obtain a polyaluminium compound having a higher molar ratio of hydroxide to aluminium than the polyaluminium compound had before contacting it with the anion exchange material.
