摘要

本研究采用聚乳酸(PLA)/氧化锌壳聚糖生物纳米复合材料开发了一种微固相萃取技术,用于从水环境中分离特定的三嗪类化合物。随后,分离出的分析物在溶剂解吸后被注入气相色谱-质谱联用仪。聚乳酸生物纳米复合材料含有不同浓度的合成 ZnO-壳聚糖,采用溶剂浇铸法制成。利用场发射扫描电子显微镜、傅立叶变换红外光谱、拉伸试验和 X 射线衍射对聚乳酸/氧化锌-壳聚糖生物纳米复合材料和氧化锌-壳聚糖杂化纳米粒子进行了分析表征。拉伸试验表明,在聚乳酸中添加 ZnO-壳聚糖杂化纳米粒子可提高聚乳酸的拉伸强度和断裂伸长率。对聚乳酸/氧化锌-壳聚糖生物纳米复合材料萃取过程中的关键参数,如纳米粒子浓度、离子强度、样品 pH 值、萃取时间和溶剂选择进行了细致的研究和优化。改进后的萃取装置具有高灵敏度和快速性,分析参数的检出限为 0.85 至 2.5 纳克/升,定量限为 5 至 10 纳克/升。在 20 分钟内达到平衡。在 10-1000 ng L-1 的浓度范围内,该方法呈线性关系,相关系数大于 0.9997。相对标准偏差在 4% 至 8% 之间,重复性在 100 纳克/升时得到确认。最终,从天然水样中成功地回收了特定的分析物,相对回收率在 98% 到 102% 之间,表明基质干扰可以忽略不计,从而证实了所建议的萃取装置的有效性。

A bio-sorbent based on polylactic acid nanocomposites for thin-film microextraction

In this work, a micro-solid-phase extraction technique employing polylactic acid (PLA)/ZnO-chitosan bio-nanocomposites was developed to isolate selected triazines from aqueous environments. Subsequently, the isolated analytes were injected into gas chromatography–mass spectrometry instrument following solvent desorption. The PLA bio-nanocomposites, incorporating varying concentrations of synthesized ZnO-chitosan, were fabricated utilizing the solvent casting method. The PLA/ZnO-chitosan bio-nanocomposites and ZnO-chitosan hybrid nanoparticles were analytically characterized by the use of field emission scanning electron microscopy, Fourier-transform infrared spectroscopy, tensile testing, and X-ray diffraction. Tensile tests showed that adding ZnO-chitosan hybrid nanoparticles to PLA increased both its tensile strength and elongation at break. Key parameters of the extraction process involving PLA/ZnO-chitosan bio-nanocomposites such as nanoparticle concentration, ionic strength, sample pH, extraction duration, and solvent choice were meticulously examined and optimized. The refined extraction device exhibited high sensitivity and rapidity, achieving analytical parameters with a detection limit ranging from 0.85 to 2.5 ng L−1 and a quantification limit between 5 and 10 ng L−1. Equilibrium was attained within 20 min. Over a concentration range of 10–1000 ng L–1, the method showed linearity, with a correlation value higher than 0.9997. Having a relative standard deviation between 4 and 8%, repeatability was confirmed at 100 ng L−1. Ultimately, the proposed extraction device’s effectiveness was confirmed by successfully recovering specific analytes from natural water samples, with relative recovery percentages ranging from 98 to 102%, indicative of negligible matrix interference.
