AB  - Adsorption of arsenic (V) from aqueous solutions onto natural 
  pozzolan from Djoungo was studied. Experiments were carried out in batch as 
  a function of contact time and pH at a frequency of 7 Hz. Results showed that 
  adsorption equilibrium onto pozzolan was attained in 20 min at the pH studied 
  and kinetics followed a pseudo-second-order model. The experimental isotherm 
  data were analyzed using Freundlich, Langmuir and Redlich-Peterson isotherm 
  equations. In order to determine the best-fit isotherm for each system, non-linear 
  regressions were carried out. For this, Chi-square error was used to evaluate 
  the data. The errors values indicated that the Redlich-Peterson isotherm was 
  able to provide best quality fit for all the experimental data.
