Aluminum hydroxide gel production involves adding buffer selected from a group comprising N-morpholino ethanesulfonic acid, N-morpholino propanesulfonic acid, tris hydroxymethyl aminomethane or their mixture

NOVELTY – Aluminum hydroxide gel production involves adding buffer selected from a group comprising 2-(N-morpholino)ethanesulfonic acid, 3-(N-morpholino)propanesulfonic acid, tris(hydroxymethyl) aminomethane or their mixture, and a salt selected from a group comprising sodium chloride, sodium sulfate, potassium chloride or their mixture. The obtained mixture is cooled and homogenized by agitation during the process. USE – Method for producing aluminum hydroxide gel. ADVANTAGE – The method produces the aluminum hydroxide gel in a cost-effective manner with high electrocoagulation efficiency. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic representation of the aluminum hydroxide gel production process.
