TI  - Effects of pH and temperature on isotherm parameters of chlorophenols biosorption 
      to anaerobic granular sludge.
PG  - 398-403
AB  - As the most important parameters affecting the biosorption, pH and temperature 
      were studied in this paper in order to more completely understand their effects 
      on chlorophenols' biosorption onto anaerobic granular sludge. Sorption isotherms 
      of 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP) at various temperatures 
      were determined; the data of 4-CP could be simulated by Langmuir model, while the 
      data of 2,4-DCP could only be reproduced by Freudlich equation. The uptake 
      capacity of 4-CP and 2,4-DCP could reach 1.5mgg(-1) and 5.04mgg(-1) when 2,4-DCP 
      concentration was 90mgL(-1) and 4-CP concentration was 107mgL(-1), respectively. 
      2,4-DCP was more strongly adsorbed onto the anaerobic granular sludge than 4-CP, 
      which might be correlated with the numbers of chlorine substitute. The 
      Experiments studying pH effects showed that the adsorption capacity of 4-CP and 
      2,4-DCP was quite pH dependent and increased with decrease in pH.
