摘要：以工业废弃物焚烧产生的灰渣为主要原料,利用ICP和IC等测试手段,研究了不同配合料配比对玻璃在酸碱溶液中的重金属离子和阴离子浸出浓度的影响。实验结果表明:在p H=3和10的酸/碱性溶液中,原料的离子浸出浓度从1.45 mg/L和0.94 mg/L分别可下降到玻璃[D(1)-4]时的0.15 mg/L和0.024 mg/L;含氧化钙高的玻璃其铬离子浸出浓度[D(1)-4时的0.15mg/L]要低于含氧化铁高的玻璃[D(1)-6时的0.19 mg/L],而氯离子浸出浓度则相反(前者为0.075 mg/L,后者为0.042 mg/L)。玻璃的热膨胀系数、抗折强度和维氏硬度分别为78×10-6/℃、96 MPa和504 MPa。
The ion concentrations in the leaching solution from glasses,which were fabricated by using fly ash（ FA） and bottom ash（ BA） from incinerated industrial solid waste as main raw materials,were measured by ICP and IC. The experimental results showed that the Cr^3＋ concentrations reduced by adding SiO2 and Al2O3. The leached [Cr^3＋]in D（1）-4 Ca O-rich glass is lower than that in D（1）-6 Fe2O3-rich glass. Whereas,the leached [Cl-]in the former is higher than that in the latter. The Cr3＋concentration of the leached D（1）-4 glass in acid solution is higher than that in alkali solution. The physical properties of the D（1）-4 glass are better than ordinary window glasses.
