In situ growth of Fe₃O₄nanoparticles for dispersive magnetic micro-solid phase extraction of cadmium followed by ETAAS detection

Abstract

Dispersive magnetic micro-solid phase extraction (DM-μ-SPE) with in situ growth of Fe3O4 NPs is described for Cd determination by ETAAS.

Multifunctional Logic Operations Based Upon Congruent Ion Sensing Appended with a Strategic Molecular Device: Spectroscopic Approach

“…[14] Therefore, the designing of new and efficient chemosensors for the detection of these two environmentally and physiologically significant metal ions (Zn 2 + and Cu 2 + ) is demanding in the bio-analytical and industrial fields. The fluorometric detection of ions has always garnered special attention because of real-time monitoring with superior sensitivity, prompt response, low expense, and seamless action as compared to other traditional analytical methods like inductively coupled atomic emission spectroscopy, [15] atomic absorption spectroscopy, [16] electrothermal atomization, [17] inductively coupled plasma mass spectrometry, [18] voltammetry, [19] solid-phase extraction [20] etc. In addition, Zn 2 + is practically undetectable by magnetic signaling techniques (NMR, EPR) due to its closed shell configuration (3d 10 4s 0 ).…”

Risk assessment of trace metals in sunblock creams using DABCOnium-based ionic liquid–functionalized magnetic nanoparticles

“…9 The application of Fe 3 O 4 nanoparticles (NPs) as nanomaterial sorbents has been growing in recent years because of their unique characteristics such as large adsorption capacity, high surface-area-to-volume ratios, low adsorbent requirements, and fast adsorption rates. [9][10][11] It is possible to improve the adsorption capacity of magnetic NPs by modifying them physically or chemically with complexing agents/organic compounds. 12 As modifying materials, ionic liquids (ILs) have gained great interest because they perform well in terms of both adsorption capacity and selectivity, as well as mechanical and thermal stability.…”
