Abstract
The adsorption efficiency of As (V) ions from an aqueous solution was investigated. The adsorption experiments were carried out in a batch reactor. The effects of operating parameters; i.e. the absorbent dose (g/L), the pH, the adsorption temperature (°C), the As (V) initial concentration (ppb), and type of adsorbents, on the adsorption efficiencies were studied. A PlackettBurman experimental design was used to screen for the important factors that influence As (V) adsorption. It has been found that the most important effect on the As (V) adsorption capacity was the type of adsorbent. The factor importance could be written in descending order as follows: the type of adsorbents, the adsorbent dose, the As (V) initial concentration, the adsorption temperature, and the pH.
