Synthesis of Nano Zinc Oxide from Galvanized Industrial Waste by Using a Combination Method of SOL-Gel, Sonochemical and Calcination

Nano zinc oxide can be used as catalysts, semiconductors and antimicrobial, and can be applied in the various fields, such as cosmetics, medicines, and packaging. Nano zinc oxide can be produced through synthesis process using zinc acetate as a precursor. Until now, zinc acetate used in Indonesia has to be imported from other countries with a relatively high price. This study aims to obtain nano zinc oxide by using zinc acetate of galvanized industrial waste (zinc dross). The synthesis process of nano zinc oxide was conducted using a combination method consisting of sol-gel process - sonochemica
