Abstract

A relationship between waste-water cleaning ability and local structure of iron-containing soda-lime silicate glass, 15Na2O·15CaO·xFe2O3·(70-x)SiO2 (x = 10-50 in mass%), abbreviated as NCFSx glass, was investigated by means of 57Fe-Mössbauer spectroscopy, redox titration with KMnO4 for the determination of chemical oxygen demand (COD) and inductively coupled plasma optical emission spectroscopy (ICP-OES). Mössbauer spectra of NCFSx glass with "x" of 10 and 30 were composed of two doublets: one due to FeIIIO4 tetrahedra (Td) with isomer shift (δ) of 0. 23-0. 26 mm s- 1 and quadrupole splitting (Δ) 1. 01-1. 04 mm s- 1, and the other due to FeIIO6 octahedra (Oh) with δ of 1. 00-1. 03 mm s- 1 and Δ of 2. 03-2. 05 mm s- 1. Absorption area for FeII(Td) was decreased from 9. 7 to 6. 5 and 0. 0 % when "x" was increased from 10 to 30 and 50. A leaching test performed with 500 mL of artificial waste water and 2. 0 g of NCFS50 revealed waste-water cleaning ability of soda-lime glass, e. g., COD was reduced from 280 to 55. 2 mg L- 1 after 10 day-leaching. After 10 day-leaching, it proved that iron was dissolved into waste water to a level of 5. 37 × 10-1 mg L- 1. These results prove that organic matter could be effectively decomposed with iron-containing soda-lime silicate glass.
