Development of alum from kaolin deposit using response surface methodology

A novel approach of for the formation of Hydrated Sodium Aluminium Sulpahte (Alum) from metakaolin was employed in this study. This process was used to form alum from metakaolin. It majorly involves captivating the self generated energy as a result of acid solvating in metakaolin-water solution to supply the mixing and activation energies requirement of the process without external heat source. The study gives a regression equation for the formation of Alum at a given volume of acid per gram metakaolin, temperature of reaction and desired conversion level.
