Recent developments of hydride generation in non-atomic spectrometric methods

Hydride generation (HG) is well known as a sample introduction technique in atomic spectrometry (AS). Recently, many efforts have been made to expand HG applications in non-atomic spectrometric methods due to its abilities of effective sample matrix separation, strong anti-interference capacity and high analyte transport efficiency. This work summarizes the developments, practical applications and recent trends in non-atomic spectrometric methods coupled with HG, including fluorescence and colorimetric methods, UV-vis spectrophotometry, chemiluminescence (CL), resonance Rayleigh scattering (RRS), and surface enhanced Raman scattering (SERS). Moreover, during these years, HG has become an interesting and powerful technique in nanomaterials synthesis, which was widely used in spectral analysis. This review also shows a description of several hydride-regulated synthetic methods and their analytical applications. (C) 2019 Elsevier B.V. All rights reserved.
