    abstract = {The aim of this study was to investigate the ability of H<SUB>3</SUB>PO<SUB>4</SUB> 
  and NaOH-activated carbons derived from cassava (<I>Manihot esculenta</I>) peels 
  to remove metanil yellow dye from aqueous solution in fixed beds. The effects 
  of initial dye concentration, bed height and flow rate at natural pH on the 
  breakthrough characteristics were determined. The highest experimental values 
  for the equilibrium adsorption capacities were 19.216 and 4.118 mg g<SUP>-1</SUP> 
  for H<SUB>3</SUB>PO<SUB>4</SUB> and NaOH-activated carbon, respectively, at 
  initial dye concentrations 50,10 mg L<SUP>-1</SUP> respectively, flow rate 13.3 
  mL min<SUP>-1</SUP>, bed height 10 cm, natural pH and temperature of 28-31&deg;C. 
  Total dye removal of 12.04 and 12.90% for H<SUB>3</SUB>PO<SUB>4</SUB> and NaOH-activated 
  carbons respectively at initial dye concentrations 50 and 10 mg L<SUP>-1</SUP>, 
  respectively bed height 20 cm, flow rate 13.3 m L<SUP>-1</SUP> min, temperature 
  28-31&deg;C and natural pH were obtained. Experimental results were fitted into 
  the Thomas and Yoon-Nelson Models. The maximum adsorption capacities with respect 
  to the Thomas model (%) were 118.35 mg g<SUP>-1</SUP> for H<SUB>3</SUB>PO<SUB>4</SUB>-activated 
  carbon and 118.061 mg g<SUP>-1</SUP> for NaOH-activated carbon. For the Yoon-Nelson 
  Model, the maximum adsorption capacities were 1186.959 and 890.359 mg g<SUP>-1</SUP>, 
  respectively for the H<SUB>3</SUB>PO<SUB>4</SUB> and NaOH-activated carbons.}
