During extraction process, the adsorbent coated on the surface of the hollow fiber can be removed from the solution using tweezers without using a magnet. Additionally, the need to use a centrifuge during adsorption and desorption steps is also eliminated, thereby increasing the speed, simplicity, and efficiency of the extraction process. The nanocomposite characterized through Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and energy-dispersive x-ray (EDX) analyses to ensure its applicability. The experimental parameters were optimized by applying one-variable-at the-time (OVAT) approach. Under optimal conditions, limits of detection were achieved 16.5 mu g L-1 for Pb (II) and 20.4 mu g L-1 for Cu (II), respectively, with relative standard deviations up to 7.9% and relative recoveries in the range of 91.8%-02.2%.en10.1080/00032719.2024.2312407info:eu-repo/semantics/closedAccessHeavy MetalsHollow Fiber MembraneMagnetic Polymeric Ionic LiquidMagnetic Solid Phase Extraction (Mspe)Microinjection Sampling Injection-Flame Atomic Absorption Spectrometry (Mis-Faas)ArticleWOS:0011602895000012-s2.0-85185139072Q3N/A
