The innovation of this study was to assess which types of AC derived from three selected date stones (Species: Phoenix dactylifera; types: Ajwa, Anbari, Khudri) showed better performance for the adsorption of organochlorine pesticides from contaminated water (outflow water from WWTP and agricultural effluent). In the bed column, the first experiments demonstrated that AC prepared from Ajwa date stones has a high efficiency to eliminate OCPs from an aqueous solution that 10 g of adsorbent was treated with 12 L of contaminated water. Therefore, the effects of the adsorbent mass of the material prepared from Ajwa date stones and flow rate of organochlorine pesticides onto prepared activated carbon were studied; the optimum adsorption capacity for all studied organochlorine pesticides from the water having a natural pH has reached 70–100%, using a 50 g of adsorbent in the particle size range of 0.75–100 mm, a flow rate of 2.5 mL/min, and an inlet concentration 57 µg/L. Finally, this AC proved its effectiveness to control water pollution by OCPs for agricultural and WWTPs effluents.

这项研究的创新之处在于评估从三种选定的枣核石中提取出哪种类型的交流电（物种：凤凰果；类型：Ajwa，Anbari，Khudri）对污水（污水处理厂和农业废水的出水）中有机氯农药的吸附性能更好。在床柱中，最初的实验表明，用10 L吸附剂用12 L污水处理过的水溶液，用Ajwa枣石制得的AC具有从水溶液中消除OCP的高效性。因此，研究了Ajwa大枣石制得的材料的吸附质量和有机氯农药流速对制得的活性炭的影响。使用50 g粒径范围为0.75–100 mm的吸附剂，流速为2.5 mL / min的50 g吸附剂，对具有天然pH值的水中所有已研究的有机氯农药的最佳吸附容量已达到70–100％。入口浓度为57 µg / L。最后，
