Abstract. A study is performed on the production of aluminum sulfate using the cementation of copper by aluminum from solutions. It is shown that the process rate is mainly affected by the copper content in the solution; then the time and concentration of sulfuric acid follow X 1 ≥ X 3 ≥ X 2 or, in the dimensional scale, Cu ≥ τ ≥ H 2 SO 4.

Aluminum Sulfate (Alum) is a widely-used and versatile industrial chemical, playing an important role in the production of many essentials seen and used every day in the home and industry. Most of the alum produced today is used in the pulp & paper industry as well as water and wastewater treatment.
Alum (papermaker's alum or aluminum sulfate) was used to precipitate the rosin onto paper, forming an alum/rosin sizing. Aluminum sulfate reacts with water—and produces sulfuric acid—and production of paper on the paper machine demanded additional alum, so papermakers often used the salt in excess.
