Alevli Atomik Absorpsiyon Spektroskopisi ile Manyetik Katı Faz Ekstraksiyonu Kullanılarak Cd(II) ve Pb(II) İyonlarının Tayini ve Türlendirilmesi

Abstract

In this study, Pb(II) and Cd(II) ions were determined by Fe3O4@G2/Npht magnetic dendrimers using the solid-phase extraction (SPE) method by flame atomic absorption spectrophotometer (FAAS). The morphological and chemical properties of magnetic dendrimers were investigated using Fourier Transform Infrared (FTIR) spectroscopy and transmission electron microscopy (TEM) techniques. The magnetic characteristics of the ferromagnetic features of the magnetic nanocomposites were validated by vibrating sample magnetometry (VSM). The heavy metal ion recovery was assessed via flame atomic adsorption spectroscopy (FAAS). To ascertain the ideal adsorption system conditions, the effects of various parameters, including pH, adsorbent dose, adsorbent time, eluent type and amount, etc., were examined. Optimum conditions for heavy metal recovery using Fe3O4@G2/Npht magnetic dendrimer were determined as pH 6.5, 1M HNO3 and 100 mg for Pb(II) and pH 7.5, 1 M HNO3 and 100 mg for Cd(II). The novel material of Fe3O4@G2/Npht magnetic dendrimer for separation and pre-concentration of Pb(II) and Cd(II) was used to natural water.
