摘要：

Water cleaning effect was investigated for iron-containing silicate glass. A leaching test for 10 days using 500 mL of simulated waste water and 2.0 g of 0.5x(Na2O center dot CaO)center dot 5Fe(2)O(3)center dot(95-x)SiO2 glass (20 <= x <= 50), abbreviated as xNCFS glass, resulted in a remarkable decrease in chemical oxygen demand (COD) from 290 to 26.7 mgL(-1). Mossbauer spectra of xNCFS glasses with x of 20, 30, 40, and 50 showed a marked decrease in the absorption area for tetrahedral Fe-II, suggesting that organic compounds responsible for high COD were decomposed as a result of the oxidation of Fe-II to Fe-III in the NCFS glass. It was concluded that NCFS glass was effective for the cleaning of environmental water polluted by organic compounds.
