Abstract
Official abstract text for this publication.
Provided is a method for treating sulfuric acid comprising the step (I) of bringing said sulfuric acid into contact with a collection of solid particles (B) having BET surface area of 50 m 2 /g to 5,000 m 2 /g and having volume-average particle diameter of 200 μm or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for treating sulfuric acid comprising the step (I) of bringing said sulfuric acid into contact with a collection of solid particles (B) having BET surface area of 50 m 2 /g to 5,000 m 2 /g and having volume-average particle diameter of 200 μm or less. 2. The method of claim 1 , wherein said solid particles (B) are activated carbon particles. 3. The method of claim 2 , wherein said sulfuric acid, prior to said step (I), has undergone a reaction with a copolymer. 4. The method of claim 2 , wherein said sulfuric acid is in the form of a solution that comprises sulfuric acid and water. 5. The method of claim 2 , wherein said activated carbon particles are powdered activated carbon particles. 6. The method of claim 2 , wherein said method further comprises the step, after said step (I), of separating said sulfuric acid from said activated carbon particles.
