Abstract: The study was done to synthesize the Potash alum from waste Aluminium foil. Potash alum IUPAC name is Aluminium potassium sulphate dodecahydrate and commonly referred to as fitkari. The used aluminium foil was washed properly and was dissolved in potassium hydroxide to form a complex aluminate. It was then filtered and sulphuric acid was added to aluminate, placed in a water bath and again filtered to obtain potash alum. The analysis of synthesized alum confirms the presence of
potassium, aluminium, sulphate and water of hydration with a melting point of 91.5 degrees Celcius. The product yield was 10.58%. The conductivity and TDS of soil sample treated with synthesized alum were 1.579 ms and 1.026 ppt with a comparison with commercial alum 6.73 ms and 4.37 ppt respectively.
Keywords: Potash alum, aluminium foil, aluminate, TDS.
