Cellulose nanoparticles are sustainable natural polymers with excellent application in environmental remediation technology. In this work, we synthesized cellulose nanoparticles and covalently functionalized them with a multi-functional group possessing ligands. The hybrid material shows excellent adsorption properties for the simultaneous extraction of multiple metal ions in the sample preparation technique. The sorbent shows excellent sorption capacity in the range of 1.8-2.2 mmol/g of material. The developed method was successfully employed for the simultaneous extraction of Pb(II), Cd(II) and Cu(II) from real-world samples (industrial effluent, river water, tap and groundwater) and subsequently determined by inductively coupled plasma optical emission spectroscopy (ICP-OES). The method shows a preconcentration limit of 0.7 ppb attributes to analyze the trace concentration of studied metal ions. The detection limit obtained for Pb(II), Cd(II) and Cu(II) is found to be 0.4 ppb.
纤维素纳米颗粒是可持续的天然聚合物，在环境修复技术中具有出色的应用。在这项工作中，我们合成了纤维素纳米颗粒，并用具有配体的多功能基团对其进行共价功能化。该杂化材料在样品制备技术中对多种金属离子的同时萃取显示出优异的吸附性能。该吸附剂在1.8 - 2.2 mmol/g材料范围内表现出优异的吸附容量。所开发的方法成功用于从实际样品（工业废水、河水、自来水和地下水）中同时萃取Pb(II)、Cd(II)和Cu(II)，随后通过电感耦合等离子体发射光谱法（ICP - OES）进行测定。该方法的预富集限为0.7 ppb，有助于分析所研究金属离子的痕量浓度。发现Pb(II)、Cd(II)和Cu(II)的检测限为0.4 ppb。
