摘要: |
研究了活性氧化铝对地下水中低浓度砷的吸附效果。结果表明,活性氧化铝对砷的吸附作用与溶液的pH值有关,pH值在5~6之间对砷的吸附率最高,最大活性氧化铝砷吸附量为75mg/g。活性氧化铝不仅对砷有吸附作用,对氟化物也有较强的吸附作用。 |

Abstract: |
The absorption of low concentration of arsenic in groundwater by activated alumina was studied here.The results showed that pH could affect the absorption.The peek of absorption happened at pH between 56 with maximum adsorption capacity as 75mg/g.It is also indicated that the activated alumina cannot only absorb arsenic,but also absorb fluoride. |
Key words: arsenic pH activated alumina adsorption |
