Síntese do Alúmen de Alumínio e Potássio a partir de latas de Alumínio

Abstract

This study investigated the feasibility of synthesizing aluminum potassium alum from recycled aluminum cans, with the aim of contributing to environmental sustainability and waste utilization through recycling. Using a literature-based methodology, experiments were conducted in the laboratory, employing analytically pure reagents and appropriate equipment. The results demonstrated an average efficiency of 77.03% in converting the reagents into the product, indicating the viability of the process at the laboratory scale and its potential for industrial application. Although the yield obtained is lower than that of commercial alum, this reveals considerable potential for improvement. Furthermore, aluminum recycling proved economically advantageous compared to extracting the metal from ores. Alum synthesis not only offers a sustainable way to utilize waste but also produces a useful byproduct, hydrogen, making it a promising alternative for obtaining industrially relevant compounds. As a suggestion for future work, further investigation into the potential of hydrogen as a renewable energy source is recommended to enhance the environmental sustainability of the process. In summary, this study represents a significant step toward seeking more sustainable solutions in the chemical industry.
