Abstract
Using aluminum beverage cans as the basic material for making alum can reduce environmental pollution due to piles of non-biodegradable waste. The product produced in this study is potassium alum, KAl(SO4)2.12H2O. This alum can help the water purification process because of its role as a coagulant. This study aimed to determine the characteristics of alum produced from the basic material of used aluminum beverage cans. The process of making alum from cans begins with cutting cans to the same size. Then, the cans were dissolved with 30% KOH with volume variations for 30 minutes and then filtered. The filtrate was re-precipitated with the addition of 30 ml H2SO4 with various concentrations. The precipitate was then washed and dried in an oven. In this study, the best results were obtained at 50 ml KOH volume with 8 M H2SO4 concentration with the characteristics of a white solid with a pH of 3,5 and a KAl(SO4)2.12H2O content of 91,9%.
