The growth of the environment depends upon developing greener and ecological methods for managing pollutants and contamination from industrial wastewater, which causes significant effects on human health. The removal of these pollutants from wastewater using nanomaterials covers an ecological method that is free from expensive and secondary pollution. In this report, we developed magnetic iron nanoparticles from (CG), which showed excellent adsorption capacity at pH 5 for selective Hg and Pb metal ions among various heavy metal ions, with maximum adsorption capacities of 96.9 and 94.1%, respectively. These metals' adsorption process conforms to the Langmuir model, which suggests that monolayer adsorption transpires on CG-FeO nanoparticles. CG-FeO nanoparticles also act as an efficient and recyclable heterogeneous catalyst for one-pot synthesis of xanthene derivatives, yielding products with high yields (up to 97%) and excellent purity (crystalline form) within a short timeframe (6 min) using microwave irradiations (at 120 W).
环境的增长取决于开发更绿色和生态的方法来管理工业废水中的污染物和污染，这对人类健康有重大影响。使用纳米材料从废水中去除这些污染物涵盖了一种生态方法，它没有昂贵和二次污染的问题。在本报告中，我们开发了一种从 (CG) 中提取的磁性铁纳米粒子，它在 pH 值为 5 时对各种重金属离子中的 Hg 和 Pb 金属离子表现出优异的吸附能力，最大吸附容量分别为 96.9%和 94.1%。这些金属的吸附过程符合 Langmuir 模型，表明在 CG-FeO 纳米粒子上发生单层吸附。CG-FeO 纳米粒子还可以作为一锅法合成呫吨衍生物的高效可回收非均相催化剂，在微波辐射（120 W）下，在短时间（6 分钟）内以高产率（高达 97%）和优异的纯度（晶型）得到产物。
