By a News Reporter-Staff News Editor at Science Letter -- Current study results on Nanoparticles have been published. According to news reporting originating from Tehran, Iran, by NewsRx correspondents, research stated, "A novel sorbent based on pyridine-2,6-diamine-functionalized Fe(3)O(4) nanoparticles was developed and characterized by X-ray powder diffraction (XRD), elemental analysis, IR spectroscopy and scanning electron microscopy (SEM). The application of the sorbent was investigated for pre-concentration and determination of lead and cadmium ions in aqueous samples."
Our news editors obtained a quote from the research from Shahid Beheshti University, "Effects of various factors such as the sample pH, eluent parameters (type, concentration and volume) and time (adsorption and desorption) were appraised. The effects of several interfering ions on method recovery were also investigated. The limit of detection (LOD) was found to be 1.3 and 0.089 ?g L(-1) for lead and cadmium ions, respectively. Recovery and precision (RSD%) of the method were above 97.9% and below 0.6%, respectively. Validation of the outlined method was performed by analysing several certified reference materials."
According to the news editors, the research concluded: "This method was successfully used for determination of lead and cadmium ions in several cosmetic samples, which are usually contaminated by lead and cadmium ions."
