Abstract
A method of forming nanoparticles from aluminum cans is provided, wherein the nanoparticles may be used to fabricate effervescent tablet for suspension production. The method includes collecting, cleaning, and drying aluminum cans; shredding and melting the aluminum cans and forming the melted aluminum cans into small parts; milling the small parts into a powder; sieving the powder to obtain a sieved powder; and ball milling the sieved powder to obtain nanoparticles. The particles may then be mixed with effervescent agents and surfactant and pressed to form the effervescent tablet. The effervescent tablet may be added to water to produce the suspension.
