| 摘 要： | 利用粉煤灰除砷,考察碱洗和负载Fe(Ⅲ)氧化物等不同的改性方法对去除As(Ⅴ)效果的影响.结果表明,经碱洗和Fe(Ⅲ)改性的粉煤灰吸附效果(平衡吸附量Qc＞ 35 mg/g)明显强于未经改性的粉煤灰(平衡吸附量Qc＜1 mg/g),在初始砷浓度为1 mg/L,pH值为中性的条件下,投加量为0.5 mg/L,24 h后砷... |

| Abstract: | Fly ash was used to remove arsenate As(V) from water,and the effects of the modification methods on the As(V) adsorption capacity of fly ash was investigated,such as alkali lye soaking and coating with Fe(III) oxide.The results showed that after both two modification processes,the adsorption effect(Qe>35 mg/g) was significantly better than the one(Qe<1 mg/g) before modification.Additionally,when the initial concentration of As(V) was 1 g/L and adsorbent dosage was 0.5 mg/L,the arsenic removal efficiency cou... |
