| 摘 要： | 通过采用不同pH值的浸出剂对淮南上窑贮灰场中粉煤灰进行了室内浸泡试验研究,得出粉煤灰中微量元素的浸出规律.结果表明:微量元素Cu,Mn,Cd,Ni,Zn随着pH值的增大析出浓度减少,而Cr随着pH值的增大溶出浓度增大,B的溶出与pH值的关系不明显;粉煤灰中微量元素溶出率很低,不会对环境造成污染.

| Abstract: | The author firstly collected fly ash in discharging coal dust field of Shang Yao, secondly did marination experiment of fly ash under different pH value condition, finally get leaching characteristics of trace elements of fly ash. She draw a conclusion that trace elements such as Cu, Mn, Cd, Ni, Zn, their separated concentration declines with pH value increasing ; the separated concentration of Cr increasing with pH value ; B has little relation to pH value ; the content of B elements separated from fly ash are little and do not polluted the environment. |
