摘要

本研究首次采用新型表面共价反应方法对聚丙烯吸附膜表面的阿塔蓬石纳米颗粒进行改性,以吸附各种小分子污染物。表面共价反应法具有步进控制的优点。因此,可以确保阿塔蓬石纳米粒子的均匀性和稳定性,从而有效提高聚丙烯吸附膜的吸附性能。另一方面,与目前在聚丙烯吸附膜表面改性的各种材料相比,纳米阿托泡石具有成本低、环境友好的特点,更有利于大规模的实际应用。采用场发射扫描电镜、傅里叶变换红外光谱仪和 X 射线衍射仪对改性后的聚丙烯吸附膜进行了表征,证实纳米阿塔波来石成功改性于聚丙烯吸附膜表面。实验结果表明,在 10 s 内,改性后的聚丙烯吸附膜对环丙氨嗪、孔雀石绿和达根安的吸附量分别达到 11.53 mg/g、8.7 mg/g 和 5.78 mg/g。同时,经过 50 次循环后,改性后的聚丙烯纳米吸附膜的吸附性能也没有明显下降。用改性后的聚丙烯吸附膜吸附黄瓜皮样品中的环丙氨嗪,其标准回收率为 76.8 % - 89.5 %,相对标准偏差为 7.2 % - 15.2 %,表明改性后的聚丙烯吸附膜具有处理复杂样品的能力。

Preparation of attapulgite nanoparticles modified polypropylene adsorption membrane and its application in small molecular pollutant adsorption
In this study, a novel surface covalent reaction method was used to modify attapulgite nanoparticles on the surface of polypropylene adsorption membrane to adsorb various small molecular pollutants for the first time. The surface covalent reaction method has the advantage of step control. Therefore, the uniformity and stability of attapulgite nanoparticles can be ensured, and then could effectively improve the adsorption performance of polypropylene adsorption membrane. On the other hand, compared with various materials modified on the surface of polypropylene adsorption membrane currently, attapulgite nanoparticles has the characteristics of low cost and environmental friendliness, which is more conducive to the large-scale practical application. The polypropylene adsorption membrane modified with attapulgite nanoparticles was characterized by field emission scanning electron microscopy, fourier transform infrared spectrometer and X-ray diffractograph, and it was confirmed that the attapulgite nanoparticles was successfully modified on the surface of the polypropylene adsorption membrane. The experimental results showed that the adsorption capacities of polypropylene adsorption membrane modified with attapulgite nanoparticles could reach 11.53 mg/g, 8.7 mg/g and 5.78 mg/g for cyromazine, malachite green and dagenan respectively within 10 s. In the case of the above three analytes, the minimum detected concentration could reach 0.02 mg/mL, and the relative standard deviation was about 10 %. At the same time, the adsorption performance of polypropylene adsorption membrane modified with attapulgite nanoparticles did not decrease significantly after 50 cycles. A standard recovery of 76.8 % − 89.5 % and a relative standard deviation of 7.2 % − 15.2 % were obtained by using the polypropylene adsorption membrane modified with attapulgite nanoparticles to adsorb cyromazine in cucumber skin samples, indicating that the polypropylene adsorption membrane modified with attapulgite nanoparticles has the ability to treat complex samples.

期刊介绍: The Journal of Chromatography B publishes papers on developments in separation science relevant to biology and biomedical research including both fundamental advances and applications. Analytical techniques which may be considered include the various facets of chromatography, electrophoresis and related methods, affinity and immunoaffinity-based methodologies, hyphenated and other multi-dimensional techniques, and microanalytical approaches. The journal also considers articles reporting developments in sample preparation, detection techniques including mass spectrometry, and data handling and analysis. Developments related to preparative separations for the isolation and purification of components of biological systems may be published, including chromatographic and electrophoretic methods, affinity separations, field flow fractionation and other preparative approaches. Applications to the analysis of biological systems and samples will be considered when the analytical science contains a significant element of novelty, e.g. a new approach to the separation of a compound, novel combination of analytical techniques, or significantly improved analytical performance.
