Spectrometric techniques for the analysis of trace lead have developed rapidly due to the increasing need for accurate measurements at extremely low levels of this element in diverse matrices. This review covers separation and preconcentration procedures, and considers the features of the application with several spectrometric techniques.

Hierarchically porous reduced graphene oxide/SnIn4S8 (RGO/SnIn4S8) composites with visible-light response and strong mineralization ability were first successfully prepared by a facile low-temperature co-precipitation method, and were characterized by X ray diffraction (XRD), scanning electron microscope (SEM), Brunauer-Emmet-Teller (BET), UV-Visible spectrophotometer (UV-Vis), Raman spectra an...

We present a novel technique for particle sizing based on recent studies about the statistical information contained within the light intensity distribution close to a disordered sample. We show that it is much simpler and more robust than the traditional light scattering methods and any imaging technique. Applications to optical diagnostics, process monitoring and pollution monitoring are expe...

This study focus on the preparation of two supports including activated carbon derived from medlar and Palladium nanoparticles loaded on activated carbon (Pd-NP-AC). Subsequently, both adsorbent modified with a novel Schiff base chelating agent and their potential applicability for determination of trace amounts of metal ions from aqueous solution has been investigated. The method is based on c...
