ABSTRACT
The agricultural wastes proposed for the removal of water pollutants in this study are seeds of two Saudi date lines which are quite abundant in the Kingdom of Saudi Arabia, having high ion exchange capacity for organic compounds. Two goals can be achieved when using these type of date stones: the first is to evaluate the potentiality of date stones to sorb inorganic and organic pollutants from drainage water to render it suitable for irrigation of crops in the Kingdom and the second is to get rid of harmful agricultural wastes. Chemical and elemental analyses were carried out for date stones. Batch technique experiments were conducted to determine the adsorption properties of date stones to harmful pesticides such as Endrin, Lindane and Aldrin. Affecting parameters such as adsorbent weight, contact time and polluted water pH values were also studied to control and increase the efficiency of adsorption. The obtained results showed that the date stones can be considered as an efficient adsorbent for the investigated pesticides from prepared waste water. The resultant uptake efficiency was found to be more than 75% for the tested pollutants. Moreover, it was found that the adsorbed pesticides can not be disturbed from the loaded date stones. Comparative methods between the Saudi and Egyptian date stones were also studied.
