This study aims to synthesize and characterize an economical and ecological adsorbent with high adsorption capacity. For this purpose, the peanut shells (Pistacia vera L.) were modified chemically. After the synthesis of activated carbon (AC), the optimum conditions for enrichment steps were performed using parameters: pH and contact time for uranium in the model solutions. The measurements were carried out by inductively coupled plasma-mass spectrometry (ICP-MS). From the shapes of the BET isotherms, the AC obtained exhibits type I. The study indicated that the surface area and total pore volume of the AC were found to be 679.9 m² g⁻¹ and 0.31 cc g⁻¹, respectively. The adsorption capacity was found to be 260 mg g⁻¹. The optimum pH was found to be 6.0 for enrichment using the AC obtained by sulfuric acid as a chemical-modifier. The optimized method was applied to enrichment of U at ppb levels in the model solutions.

本研究旨在合成和表征具有高吸附容量的经济和生态吸附剂。为了这个目的，花生壳（阿月浑子大号。）进行了化学修饰。合成活性炭（AC）后，使用参数：模型溶液中的pH值和铀的接触时间来执行富集步骤的最佳条件。通过电感耦合等离子体质谱法（ICP-MS）进行测量。根据BET等温线的形状，得到的AC显示出I型。研究表明，AC的表面积和总孔体积为679.9 m ² g ^-1和0.31 cc g ^-1， 分别。吸附容量为260mg g ^-1。发现使用硫酸作为化学改性剂获得的AC富集的最佳pH为6.0。将优化方法应用于模型溶液中ppb级U的富集。
