Abstract

BACKGROUND: The objective of this study was to evaluate the chemical extraction efficiency of five metals (Cu, Ni, Zn, total Cr, and Fe) from galvanic sludge using molasses hydrolysate produced from molasses, a by-product of the sugar industry. The study was also aimed to compare the extraction efficiency of the molasses hydrolysate with those of nitric acid and EDTA.
