Strategies for inorganic speciation analysis employing spectrometric techniques-Review

This work shows a brief revision of the analytical methods which have been recently developed for speciation studies employing non-chromatographic speciation techniques. Advantages, limitations, and applications of this technique have been discussed, including a comparison to the chromatographic speciation analysis. Additionally, procedures proposed recently for speciation analysis utilizing chemical vapor generation, ion-imprinted polymers, microorganism, selective chemical reactions, and separation techniques have been highlighted, evidencing advantages, and drawbacks. The advantages and applications of the XANES spectroscopy as a technique for speciation analysis are also described.
