Silver Nanoparticles for the Adsorption of Manganese from Biological Samples

Abstract

In this study, silver nanoparticles were prepared and used for separation and preconcentration of manganese from biological samples. The technical feasibility of silver nanoparticles for manganese removal was investigated under batch studies. The effects of different parameters such as pH of solution, time (t), amounts of PAN (E), and silver nanoparticles (N) on the adsorption of manganese by silver nanoparticle were investigated using factorial design and response surface methodology based on Box-Behnken design. Thermodynamic parameters indicate the adsorption process to be exothermic. The limit of detection of the proposed method followed by inductively coupled plasma was found to be 0.08 µg L(-1). The method was applied to determine of manganese in biological samples.

Nanoadsorbents: Classification, Preparation, and Applications (with Emphasis on Aqueous Media)

“…Recently, NPs have been used as sorbents due to their better intrinsic properties, such as chemical activity and fine grain size, as compared with the classic substances including normal scale titanium dioxide, alumina, etc. ,, NPs can be chemically modified by a reagent to obtain a new selective solid phase extractant for the preconcentration of metal ions. − …”

Mechanism and behavior of silver nanoparticles in aqueous medium as adsorbent

“…The demands of chemical analysis in modern biology, environmental science, chemistry, medicine, and industry need very high sample throughput and parallel analytical strategies [119][120][121][122][123]. While the increasing role of AgNPs in separation and pre-concentration science is evident, the future will need greater control over their size and composition.…”

Silver nanoparticles for separation and preconcentration processes

“…A simple and fast method for preconcentration and determination of trace amounts of manganese [31] and lead [32] in biological samples was developed with modified AgNPs followed by inductively-coupled plasma optical emission spectrometry (ICP-OES) for manganese, and graphite-furnace atomic absorption spectrometry (GF-AAS) for lead. The technical feasibility of AgNPs for manganese removal was investigated in batch studies.…”
