X-ray spectrometry and X-ray diffraction (XRD) studies indicate that yellow sludge containing hydroxides of several hazardous heavy metal ions, i.e., Cr, Fe, Cu, Zn and Pb, has an amorphous structure. The XRD and 57Fe Mössbauer studies of the yellow sludge indicate the formation of a small amount of γ-FeOOH particles. Heavy metal waste glass of a light green color could be prepared by melting the yellow sludge together with synthetic soda-lime silicate glass of a light brown color. Additional waste glass could be prepared from a glass bottle for commercial drinks. Leaching test for Zn and Fe with the acid rain simulant (pH 3.5), which was prepared from a nearly equal amount of HNO3 (pH 3.5) and H2SO4 solution (pH 3.5), proved that the waste glass has higher chemical durability than the sludge adsorbed on “diatomaceous earth.” These results indicate that soda-lime silicate glass is a very effective medium for stable solidification of heavy metal ions, and that the “glass wastes” can be reused for this purpose.
