Two green methods (microwave and hydrothermal) were employed for the preparation of water dispersible fluorescent carbon nanoparticles (CNPs) from activated charcoal. Microwave and hydrothermally synthesized carbon nanoparticles, (MW-CNPs) and (HT-CNPs), respectively were characterized by microscopic and spectroscopic techniques. A detailed study of their fluorescence characteristics was made. MW-CNPs and HT-CNPs were tested for metal ion selectivity in aqueous medium. MW-CNPs showed selectivity for Fe among the tested metal ions and important studies such as for interference, linear range and limit of detection were carried out. The application of MW-CNPs for detection of Fe in water was demonstrated.
采用两种绿色方法（微波法和水热法）从活性炭制备水分散性荧光碳纳米颗粒（CNPs）。分别通过显微镜和光谱技术对微波合成的碳纳米颗粒（MW-CNPs）和水热合成的碳纳米颗粒（HT-CNPs）进行了表征。对它们的荧光特性进行了详细研究。测试了MW-CNPs和HT-CNPs在水介质中的金属离子选择性。MW-CNPs在测试的金属离子中对Fe表现出选择性，并开展了诸如干扰、线性范围和检测限等重要研究。证明了MW-CNPs在水中检测Fe的应用。
