Abstract

Among the many drawbacks of the current wastewater treatment systems are their high energy consumption and creation of harmful sludge. Carbon nanotubes (CNTs) are advantageous for the treatment of water due to their strong adsorption capacity and selectivity towards various pollutants. Thus, creating methods for treating water by producing CNTs from Moringa oleifera leaf extract can greatly help with the clean water problem. The synthesised material’s Ultra Visible (260–385 nm), FTIR (764–3295 cm−1) and Scanning Electron Microscope (SEM) characterizations have demonstrated their CNTs characteristics. The repeatability testing yielded the %RSD values for Ca = 0.4, Cu = 0.24, Mg = 0.9, Pb = 1.06 and Zn = 0.36 which suggest that the AES approach demonstrated a high degree of precision. The findings show that the quantity of recovered metals increases with retention period. Mg > Cu > Zn > Ca > Pb was the order of the metal adsorption capacity throughout retention durations of 3, 6, 24, and 48 h. As the initial concentrations of the components under research were doubled and tripled, so were the removal capacities of CNTs increased which may be as a result of an increase in metal ions in the solution. The outcomes show how well the synthetic CNTs can remove heavy metals from wastewater.

从油辣木叶提取物中提取的绿色合成碳纳米管作为潜在有毒金属吸附剂在污染水体中的效率

目前的废水处理系统有许多缺点，其中包括能耗高和产生有害污泥。碳纳米管（CNT）具有强大的吸附能力和对各种污染物的选择性，因此在水处理方面具有优势。因此，通过利用辣木叶提取物生产碳纳米管来创造水处理方法，对解决清洁水问题大有帮助。合成材料的超可见光（260-385 nm）、傅立叶变换红外光谱（764-3295 cm-1）和扫描电子显微镜（SEM）特性均证明了其 CNTs 特性。重复性测试得出了 Ca = 0.4、Cu = 0.24、Mg = 0.9、Pb = 1.06 和 Zn = 0.36 的 %RSD 值，表明 AES 方法具有很高的精确度。研究结果表明，金属回收量随保留时间的延长而增加。在 3、6、24 和 48 小时的保留时间内，镁、铜、锌、钙、铅的金属吸附能力依次增加。随着研究成分的初始浓度增加一倍和两倍，CNT 的去除能力也随之增加，这可能是溶液中金属离子增加的结果。这些结果表明了合成 CNT 清除废水中重金属的能力。

期刊介绍： Pure and Applied Chemistry is the official monthly Journal of IUPAC, with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union. The policy is to publish highly topical and credible works at the forefront of all aspects of pure and applied chemistry, and the attendant goal is to promote widespread acceptance of the Journal as an authoritative and indispensable holding in academic and institutional libraries.
