Abstract

Aluminum cans are one type of heavy metal whose presence is increasing from year to year as inorganic waste which has bad potential for the environment, besides that the recycling process of waste is also lacking. In this study using aluminum cans waste for raw materials from making (KAl(SO4)2.12H2O) as an effort to recycle aluminum cans waste because it is known that the aluminum content contained in cans is about 87%. Alum is currently needed in the industrial sector to be used for processing wastewater. How to process the alum by reacting aluminum with KOH variations of 20%, 30%, and 40%. Then a 7M H2SO4 solution is added to form crystalline alum deposits. The purpose of this study was to determine the effect of the concentration of KOH on the value of aluminum and iron content contained in alum, the value of drying losses, and the value of substances that are not soluble in water as listed in SNI 06-2102-1991. Alum weight produced from 2 grams of most aluminum canned waste is at 40% KOH concentration as much as 36,8 grams with iron candles of 0,004%, 2,2% aluminum content, 8,33% water content, and water insoluble substances 2,584%.
