Abstract

A branched polyethyleneimine (PEI) and polyacrylonitrile (PAN) composite nanofibers has been synthesized via electrospinning for the solid phase extraction (SPE) of trace metal ions. The synthesized fibers have been analyzed for structural and morphological characteristics by FTIR, SEM, EDS, and XPS techniques. Measurements of the sessile drop water contact angle and zeta potential have been performed to assess surface properties. The synthesized fibers have been investigated for solid-phase extraction (SPE) and preconcentration of Pb(II), Cd(II), and Cu(II) from various water sources, followed by their quantification using inductively coupled plasma optical emission spectroscopy (ICP-OES). Under optimum conditions, the fibrous sorbent demonstrates low detection limits of 0.020–0.028 μg L⁻¹ and a broad linear range for the targeted metal ions. The analysis duration was rapid, taking 2.5 min for both adsorption and desorption. The PAN-PEI fibers can be reused a minimum of 35 times without diminishing extraction efficiency. The suggested analytical method's accuracy was validated through the analysis of recovered amount after spiking the real samples.

单步静电纺柔性聚丙烯腈-共聚乙烯亚胺纳米纤维同时萃取铅、镉和铜离子

采用静电纺丝法合成了支化聚乙烯亚胺（PEI）和聚丙烯腈（PAN）复合纳米纤维，用于固相萃取（SPE）痕量金属离子。利用FTIR、SEM、EDS和XPS等技术对合成纤维的结构和形态特征进行了分析。测量了固定水滴接触角和zeta电位，以评估表面性质。研究了合成的光纤对不同水源中Pb（II）、Cd（II）和Cu（II）的固相萃取（SPE）和预富集，并利用电感耦合等离子体发射光谱（ICP-OES）对其进行定量分析。在最佳条件下，纤维吸附剂对目标金属离子的检出限为0.020 ~ 0.028 μg L−1，线性范围宽。分析时间短，吸附和解吸均为2.5 min。PAN-PEI纤维可重复使用至少35次而不降低提取效率。通过对实际样品加峰后的回收率分析，验证了所提分析方法的准确性。

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
