|Study on Removement of Trace Arsenic in Groundwater by Activated Alumina
Fuxin Environmental Monitoring Central Station， Fuxin，Liaoning 123000，China
|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.
