title: [Study on removal of arsenic in drinking water by metal loaded materials].
abstract: OBJECTIVE
  To study the effect of metal loaded multiporous materials on the removal of arsenic in drinking water.
  
  
  METHODS
  Metal loaded materials were manufactured using active carbon, active alumina, silica gel and macroporous resin etc. as carriers and iron salts and zirconium salts etc. as activating reagents. Preparation condition as well as static and dynamic capacities of arsenic removal were examined.
  
  
  RESULTS
  Active carbon and ferric nitrate were selected to prepare composite material for removal of arsenic in drinking water. Based on the state applicable limit of 0.05 mg/L for arsenic in drinking water, iron loaded active carbon tested in this study reduced arsenic at capacities of 2.94 mg/g for As(+3) and 2.56 mg/g for As(+5) in drinking waters spiked with 0.284 mg/L of As(+3) and 0.254 mg/L of As(+5) respectively.
  
  
  CONCLUSIONS
  Iron loaded active carbon made from active carbon and ferric nitrate may remove arsenic in drinking water.
