Abstract

The effectiveness of MgO nanostructures for removing indigo carmine (IC) dye from an aqueous solution is demonstrated in this article. The nanomaterials were synthesized using MgCl2.2H2O and NaOH in a medium containing Pimpinella anisum extract. The microstructure of the samples was investigated using XRD, SEM, EDX, BET, and FTIR. Additionally, the IC dye uptake and adsorption processes were investigated using a MgO sorbent. To synthesize the MgO1 and MgO2 materials, the adsorption kinetics of IC dye, the starting pH of IC dye solution, and contact time were optimized. The maximal theoretical adsorption efficiency of the MgO1 and MgO2 adsorbents for IC dye was 559.2 and 492.6 mg/g, respectively, according to the Langmuir isotherm adsorption model. Further, recycling the MgO1 adsorbent proved conceivable due to its ease of collection and re-use following five adsorption-regeneration cycles.
利用茴香皮条虫提取物制备的MgO纳米结构吸附靛蓝胭脂红色素
本文证明了MgO纳米结构从水溶液中去除靛蓝胭脂红(IC)染料的有效性。使用MgCl2.2H2O和NaOH在含有茴香Pimpinella提取物的介质中合成纳米材料。利用XRD、SEM、EDX、BET和FTIR对样品的微观结构进行了研究。此外,使用MgO吸附剂研究了IC染料的吸收和吸附过程。为了合成MgO1和MgO2材料,对IC染料的吸附动力学、IC染料溶液的起始pH和接触时间进行了优化。根据Langmuir等温线吸附模型,MgO1和MgO2吸附剂对IC染料的最大理论吸附效率分别为559.2和492.6mg/g。此外,由于MgO1吸附剂在五个吸附-再生循环后易于收集和重复使用,因此证明回收MgO1吸收剂是可行的。
