Abstract
The adsorption performance of date stones was evaluated by varying experimental conditions such as, contact time, pH, adsorbent dosage, temperature and phenol initial concentration. The response of carbonized date stone “efficiency” was analyzed as a function of the experimental parameters (contact time, pH, adsorbent dosage, pollutant initial concentration and temperature), using the complete factorial design of 32 experiments. The response has been described by a first order model that was adequate to predict responses in all experimental regions. The experimental values obtained were in good agreement with the values predicted from the model, with relatively small errors between the predicted and the actual values. Through this study, we have confirmed that the activated carbon derived from date stones has a large capacity for adsorption, making it an effective and inexpensive adsorbent in the removal of phenolic compounds in aqueous solutions Removal of pollutant was observed to be most effective at lower pH. The maximum adsorption yield was 90.165% with the initial concentrations ranging from 10 to 50 mg/L. The adsorption reaches 82.388% with a maximum capacity of 2.032mg/g after 220 minutes
