Preconcentration of metal ions using Ferula golbaniflua-gum-Co۳O۴ nano magnetic hydrogel to their determination by ICP-OES

In this study, a hydrogel embedded with magnetic cobalt nanoparticles was synthesized from natural Ferula golbaniflua-gum through a simple and low-cost method and its potential for separation and preconcentration of lead, copper, chromium, nickel, and cadmium ions was investigated. Determination of the extracted metal ions was carried out using inductively coupled plasma/optical emission spectroscopy (ICP-OES). The magnetic property of the hydrogel helps the separation from the solution and improves the adsorption capacity. The proper synthesis of the magnetic hydrogel was confirmed with different characterizations techniques, such as Fourier transform infrared spectroscopy, VSM pattern of magnetic Ferula golbaniflua-gum-Co۳O۴ and X-ray diffraction spectrum of synthesized nanoparticles.
