摘要

本文介绍了两种活性炭的合成方法。由于活性炭(AC)具有去除空气和水中污染物的能力,因此通常用于净化。它的多孔结构允许它捕获杂质,它经常被建议用于各种水和废水处理应用。但是,由于提交AC申请的费用很高,因此可以提交的申请数量有限。本研究利用当地可获得的Peltophorum pterocarpum(铜荚)和Phoenix dactylifera(枣树)种子制备AC。以紫檀和凤凰花为原料合成样品的物理活性炭对氟的吸附。采用批量吸附法对人体物理活性炭中的氟进行了脱除,以寻找最佳的吸附时间、剂量、pH吸附动力学和吸附平衡。结果表明,理想的接触时间为30 min、吸附剂投加量为140 mg、8.00,吸附剂投加量为50 min、225 mg、9.00,除氟效率分别为77.5%、79.33%、82.6%和72.63%、75.8%、76.5%。通过改变吸附时间和用量等工艺因素,考察吸附动力学和吸附等温线模型。Langmuir, Freundlich和Temkin的等温线是三位科学家使用的实验数据,已经确定是准确的。

Activated Carbon Derived from Peltophorum pterocarpum (Copper Pod) Seeds and Phoenix dactylifera (Date Plam) Seeds in Batch Comparative Adsorption Studies of Fluoride
A synthesis of two forms of activated carbons is included in this paper. Because of its capacity to remove contaminants from both air and water, activated carbon (AC) is commonly employed for purification. Its porous structure allows it to trap impurities, and it is frequently suggested for a variety of water and wastewater treatment applications. However, due to the high expense of filing an AC application, the number of applications that can be filed is limited. AC was made using locally accessible Peltophorum pterocarpum (Copper Pod) and Phoenix dactylifera (Date Plam) seeds in this study. Fluoride adsorption on physical activated carbon from a synthetic sample made from Peltophorum pterocarpum (Copper Pod) and Phoenix dactylife. To remove fluorine from the body physically activated carbon, adsorption in batches methods were completed in order to find the best time, dose, pH sorption kinetics, and sorption equilibrium. The ideal contact duration, dosage of adsorbent and carbon pH were found to be 30 minutes, 140 mg, and 8.00, and 50 minutes, 225 mg, and 9.00, with fluoride removal efficiency of 77.5 percent, 79.33 percent, 82.6 percent, and 72.63 percent, 75.8%, 76.5 percent, respectively. Changes in process factors such as adsorption time and dosage were recycled to inspect adsorption kinetics and sorption isotherm models. The isotherms of Langmuir, Freundlich, and Temkin are three scientists investigated using This experimental data has been determined to be accurate.
